Adhesive sheet, adhesive agent composition, and structure

An adhesive sheet of which breaking elongation is 60% or more, wherein

• the adhesive sheet contains an epoxy resin, an acryl resin, a curing agent, and an inorganic filler;
• the epoxy resin includes a bisphenol A-type epoxy resin, and a three functional or more epoxy resin;
• and
• a content of the inorganic filler is 30.0 mass % or more and 68.0 mass % or less.

An adhesive sheet to be used for adhering a first member and a second member, wherein

• a tensile elastic modulus of the first member is smaller than a tensile elastic modulus of the second member;
• a breaking elongation of the adhesive sheet is 60% or more;
• a tensile elastic modulus of the adhesive sheet after cured is the tensile elastic modulus of the first member or more;
• and
• a tensile shearing adhesive strength of the adhesive sheet after cured is 10 MPa or more.
