To provide an anisotropic electroconductive adhesive film which can prevent the deformation during heat treatment, and can impart an excellent cutting characteristics, by using a biodegradable film as a release film and a method for manufacturing the anisotropic electroconductive adhesive film.
The anisotropic electroconductive adhesive film comprises a first release film 2 having a first releasing layer 5 on one surface thereof, an adhesive layer 3 composed of the anisotropic electroconductive adhesive material formed on the first release film 2 through the first releasing layer 5, a second releasing film 4 formed via the second releasing layer 6 on the surface of the opposite side of the first releasing film 2 side of the adhesive layer 3 having a second releasing layer 6 on one surface, wherein the first and the second releasing film 2, 4 are composed of a nonshrink biodegradable film comprising an aliphatic polyester component as a base and having the first releasing layer 5 and the second releasing layer 6 comprising a silicon resin hardening 100C on each base.
