Provided is an adhesive composition containing a component (A) being a modified polyolefin resin and a component (B) being a polyfunctional epoxy compound, said adhesive composition being characterized by having a storage elastic modulus of 0.1-600 MPa at 23°C and a storage elastic modulus of no more than 0.1 MPa at 80°C, when the storage elastic modulus is measured for the solid content of the adhesive composition. Also provided are: a sealing sheet having an adhesive layer formed using this adhesive composition; and a sealed body comprising an object-to-be-sealed that has been sealed by this sealing sheet. As a result of the present invention, provided are: an adhesive composition that is readily molded into a sheet shape and has excellent conformability to unevenness; a sealing sheet formed using this adhesive composition and having an adhesive layer having excellent conformability to unevenness; and a sealed body comprising an object-to-be-sealed that has been sealed using the sealing sheet.
