Abstract:
1. A circuit board comprising: a first circuit member having a first connecting terminal; and a second circuit member having a second connecting terminal; said first connecting terminal and the second connecting terminal being disposed facing each other, and an adhesive being put between the first connecting terminal and the second connecting terminal which are disposed facing each other; and said first connecting terminal and the second connecting terminal disposed facing each other being electrically interconnected by pressing; said adhesive being an adhesive film for bonding circuit members, said adhesive film being adapted to be put between circuit electrodes facing each other, with said circuit electrodes facing each other being pressed interposing the adhesive film between them, to interconnect the electrodes electrically in the direction of pressing, wherein said adhesive film comprises: a first adhesive layer which includes an adhesive resin composition and an insulative inorganic filler; said insulative inorganic filler being contained in an amount of from 10 to 200 parts by weight based on 100 parts by weight of the adhesive resin composition; and the adhesive film further comprising conductive particles in an amount of from 0.1 to 30 parts by volume based on 100 parts by volume of the adhesive resin composition.
