Abstract: Described is an electrically conductive bonding film useful in bonding an IC or LSI with a lead frame. The film comprises (A) a polyimide resin obtained by reacting a tetracarboxylic dianhydride component, in which the content of a tetracarboxylic dianhydride represented by the following formula (I): ##STR1## wherein n stands for an integer of 2-20 amounts to at least 70 mole %, with a diamine; (B) an electrically conductive filler, and a thermoset resin. Optionally, the film may further comprises a thermosetting resin or an imide compound having at least two thermally-crosslinking imido groups per molecule.
