In an embodiment, an adhesive sheet has an expandable adhesive layer 2 on one side or both sides of a base 1, wherein the expandable adhesive layer 2 contains an epoxy resin including a polyfunctional epoxy resin, a phenol resin as a curing agent, an imidazole-based compound as a curing catalyst, and a temperature-sensitive foaming agent. The adhesive sheet has properties in good balance, such as fast curability, heat resistance, and adhesiveness, and also excellent properties such as thermal conductivity attributed to a good filling property.
