The invention offers an anisotropic electroconductive sheet suitable for connecting with pin electrodes of a through-hole-mounting type. The sheet has electrical conductivity in the direction of thickness. The sheet comprises a base film formed using a porous film (1) that is made of synthetic resin and that has electrically insulating property. The porous film (1) is provided with a plurality of holes (3) that are formed in the direction of thickness so that pin electrodes (2) can be through-hole-mounted. The inner walls of the holes (3) are coated with metals (4). The inserted pin electrodes (2) become electrically continuous, through the metals (4), with the surface opposite to the surface from which the pin electrodes (2) are inserted. It is desirable that a porous film have, at the side from which the electrodes are through-hole-mounted, a nonporous film that is made of synthetic resin and that has electrically insulating property and the nonporous film be provided with a plurality of holes that are formed in the direction of thickness so that the pin electrodes can be through-hole-mounted.
