Provided is a PSA sheet that provides reliable adhesion even upon contact with grease. Provided is an adhesively double-faced PSA sheet having a PSA layer. The PSA sheet has an initial push-peel strength of 0.5 MPa or greater. It has an adhesive strength retention rate of 25% or higher, determined as the ratio of the push-peel strength at 24 hours after artificial sebum application to the push-peel strength before the artificial sebum application. |
