<p>PROBLEM TO BE SOLVED: To provide an adhesive composition for electronic appliances, which allows a product, that is obtained by sticking large-sized adherends to each other by using the composition and heating/curing the used composition, to be excellent in temperature cyclability and long-term heat resistance, and to provide an adhesive sheet for electronic appliances, which is obtained by using the adhesive composition for electronic appliances.SOLUTION: The adhesive composition for electronic appliances contains a thermoplastic resin (a), an epoxy resin (b) and a curing agent (c). The thermoplastic resin (a) has Tg (glass transition temperature) equal to or lower than -30°C and 800,000-1,500,000 weight-average molecular weight. The adhesive composition for electronic appliances contains 400-1,000 pts. wt. of the thermoplastic resin (a) on the basis of 100 pts. wt. of the total of the epoxy resin (b) and the curing agent (c). A cured product, which is obtained by curing the adhesive composition for electronic appliances at 70-100% curing reaction ratio while being measured by a differential scanning calorimeter, has the storage modulus equal to or lower than 3 MPa at 25°C.</p> |
