Patent ID: 8252419

Claim:
A circuit board comprising: a first circuit member having a first connecting terminal; and a second circuit member having a second connecting terminal, the 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 facing each other, the first connecting terminal and the second connecting terminal disposed facing each other being electrically interconnected by pressing, wherein the adhesive comprises: one adhesive layer having a modulus of elasticity of from 100 to 2000 MPa at 40° C. after curing; and another adhesive layer having a modulus of elasticity of from 500 to 5000 MPa at 40° C. after curing, which is higher than that of the one adhesive layer, the adhesive being disposed in such a way that the another adhesive layer is applied on the side of one of said circuit members which has a higher modulus of elasticity than that of the other, and the one adhesive layer is applied on the side of the other circuit member having a lower modulus of elasticity.
