Abstract

The present invention addresses the problem of providing an adhesive sheet capable of ensuring the flexibility of an adhesive layer at a low temperature and suppressing variations in the degree of deformation even when the adhesive layer deforms within a predetermined temperature range. [Solution] An adhesive sheet having an adhesive layer for bonding a first member and a second member, in which the Shore hardness of the adhesive layer at-20 DEG C as measured by an E-type durometer is 70 HS or less, and the recovery rate of the adhesive layer at 23 DEG C is 70% or more.
