Abstract:
A wiring board is manufactured by a step of forming a meshy cylindrical body, where plural conductive rings are connected to each other at plural positions in the respective peripheral direction, a step of forming laminated meshy sheets, by squashing the meshy cylindrical body in the radial direction, a step of inserting an insulation sheet between the meshy sheets, and a step of forming lacking portions at a position in the peripheral direction of conductive rings of the meshy sheets. It becomes possible to directly join a semiconductor chip to the conductive ring of the meshy sheet, and therefore, a wiring circuit can be obtained without using a solder joint.
