PROBLEM TO BE SOLVED: To provide a conductive sheet, for electric inspection, which can be used independently of the pattern of an object to be inspected and which can deal with the pattern which is highly finer than that in conventional cases and to provide its manufacturing method. SOLUTION: Conductive patterns 321 are formed on an insulating substrate 311. The prescribed number of insulating substrates 311 on which the patterns 321 are formed is laminated, heated, pressurized and molded. A laminated block 330 is manufactured.

PURPOSE:To make a preparation work easy and speedy and also to enable a prevention of error generation by making inspection points not positioned on grid points which are classified from the inspection points extracted from the connection informations of a wiring circuit board, to move to the grid point most adjacent thereto. CONSTITUTION:The connection informations such as wiring information, net information, land information, etc., from a CAD system used for the arrangement and wiring design of an object to be inspected, are inputted in a data input means 1. The inspection points are extracted therefrom in an arithmetic process means 5 and also the classification is made whether these points are positioned on the grid points settled beforehand or not, then the inspection points not positioned on the grid points are moved to the most adjacent one among the vacant grid points. The movement information of the inspection points is outputted by a magnetic disk device or a printer based on the movement result. Also, the result processed in the means 5 is stored in a storage means 4 as data base.

PROBLEM TO BE SOLVED: To drastically reduce inspection time by reducing the diameter of a probe and applying to finer inspection objects in electricity inspection for high frequency by simultaneous contact. SOLUTION: The coaxial probe for electricity inspection of this invention is constituted of a conductor cable 1, an insulation coating layer 2 covering the outside of the conductor cable 1, a conduction coating layer 3 covering the outside of the insulation coating layer 2, and an outer insulation layer 4 covering the outside of the conduction coating layer 3. On one end of the probe, the tip end of only the conduction cable 1 in the center is projected more than the outer coating layers, so as to be easy to be brought into contact with a body to be inspected. At the other end of the probe, the conduction cable 1 in the center is longest, and other coating layers are shorter for outer side, so that the conduction cable 1 in the center and the conduction layer 3 are easily connected to individual electrodes.

CONSTITUTION:An upper surface terminal 18 is provided in an upper surface. A lower surface terminal 19 is provided in a lower surface. Furthermore, one or more intermediate conductor layers are provided between the upper surface and the lower surface. The intermediate conductor layer is electrically conducted to the upper surface by way of through holes and also electrically conducted to the lower surface by way of through holes. In this way, the terminal 18 and the terminal 19 are electrically conducted through the intermediate conductor layer. Anisotropic conductive rubber sheets 17 are assembled on the surface of the upper surface and on the surface of the lower surface. Thus this device is utilized as a converter device 11. When grid-shaped probes 31 are compressed, they are electrically connected to measuring points 22 surely by the action of the springs of the probes 31. Under this state, short circuits and open states between the intended measuring points can be examined by examining short circuits and open states between the probes 31.
