Abstract: Provided is an adhesive composition containing component (A) (a modified polyolefin-based resin) and component (B) (a polyfunctional epoxy compound), wherein as a result of measuring a storage elastic modulus of a solid content, a storage elastic modulus at 23° C. is 0.1 to 600 MPa, and a storage elastic modulus at 80° C. is 0.1 MPa or lower. Also provided are: a sealing sheet having an adhesive layer formed using the adhesive composition, and a sealed body comprising a seal object that is sealed with the sealing sheet. The adhesive composition is easy to form into a sheet and excellent in unevenness followability. The sealing sheet has an adhesive layer which is formed of this adhesive composition and is excellent in unevenness followability, and a sealed body has a seal object sealed with the sealing sheet.

Abstract: Disclosed is an adhesive composition having components (A), (B) and (C): Component (A): modified polyolefin-based resin, Component (B): polyfunctional epoxy compound, and Component (C): imidazole-based curing catalyst. Also provided is a sealing sheet composed of two release films and an adhesive layer sandwiched between the release films, wherein the adhesive layer is made by using the adhesive composition and has a thermosetting property. Also disclosed is a sealed body obtained by sealing a seal subject with the sealing sheet. The adhesive composition has excellent adhesion strength, a sealing sheet made by using the adhesive composition and having an adhesive layer is excellent in sealing performance, and a sealed body obtained by sealing a seal subject with the sealing sheet.
