Abstract
An isotropically electroconductive resin film material produced by sticking electroconductive particles to a sticking layer formed on a support and fixing therein, and filling a film-forming resin incompatible with the sticking material among the electroconductive particles, has electroconductivity only in the film thickness direction via the electroconductive particles uniformly dispersed in the plane direction, and is suitable for electrically connecting oppositely placed circuits and fine electrodes of a plurality of electronic parts, and for testing electronic parts.
