    Abstract: (1) A membrane switch comprising paired plates and a spacer separating the plates from each other, wherein an operating force of the switch is 0.03 to 0.2 kg when the switch is pressed by a round bar having a hemispherical tip end with a radius of curvature of 5 mm. A production method, wherein (2) the spacer is in a film form and has through holes having a rate of hole area of not smaller than 50 % and (3) the thickness of the spacer and the size of the through holes in the spacer are set to preset values so as to provide an operating force of 0.03 to 0.2 kg, (4) the thickness of the spacer being 20 to 150 mu m, one of the sizes of through holes being 2 to 10 mm square and (5) a spacer having an insulating film of a specified thickness in which specified through holes are drilled, thereby providing a membrane switch free from erroneous operation, small in operating force change and excellent in durability.

    Abstract: An anisotropic conductive film, and its production method, especially suitable for mounting a semiconductor package and sufficiently satisfying the requirements of higher density mounting because short circuit does not occur in the plane direction of the film even if the pitch of electrodes is small, or suitable for mounting a contact probe because conductive connection not fused with a high current can be ensured with a lower pressure and even a high frequency signal can be dealt with. The anisotropic conductive film contains metal powder having such a shape that many fine metal particles are linked as a conductive component, wherein the length of the chain of metal powder is set not longer than the distance between adjacent electrodes being bonded conductively when a semiconductor package is mounted, and the diameter of the chain is set in the range of 1 mu m-20 mu m when a contact probe is mounted. At least a part of the film is formed while orienting a chain formed of a paramagnetic metal with a magnetic field.
