    摘要: A pressure-sensitive adhesive sheet includes a substrate and a pressure-sensitive adhesive layer in order toward one side in a thickness direction. The substrate contains a first β-1,3-glucan derivative obtained by introducing an acyl group into a β-1,3-glucan and at least one resin selected from the group consisting of a rosin-based resin, a terpene-based resin, and a petroleum-based resin. In the first β-1,3-glucan derivative, the acyl group is represented by R 1 CO-. The R 1 is a hydrocarbon group having 1 or more and 5 or less carbon atoms.
