Abstract:
1. A method for manufacturing an anisotropic conductive adhesive sheet comprising at least a curing agent, a curable insulating resin, and conductive particles, said method comprising providing an adhesive layer on a biaxially stretchable film to form a laminate, densely packing conductive particles having an average particle size of 1 to 8 μm on the laminate to form a conductive particle-attached film, biaxially stretching and holding the conductive particle-attached film so that the average particle distance between adjacent conductive particles is one to five times the average particle size of the conductive particles and not greater than 20 μm, and transferring the conductive particles to an adhesive sheet containing at least a curing agent and a curable insulating resin and having a thickness of at least 1.5 times the average particle distance between the conductive particles but not greater than 40 μm.
