(57) [Summary] An object of the present invention is to provide a film adhesive having both fluidity, strength, and appropriate tackiness. An adhesive composition comprising, as an essential component, a mixture of two kinds of resins A and B that phase-separate in a B-stage state, Resin A has a weight average molecular weight of 10,000 or less in an uncured state, The resin B has a weight average molecular weight of 100,000 or more in an uncured state, is continuously present as a continuous phase in the B stage, and is dispersed as a dispersed phase in the B stage. The adhesive composition is characterized in that the volume ratio of the and the continuous phase is 1: 0.5 to 5. |
