Abstract: The problem of the present invention is to provide a pressure-sensitive adhesive sheet for skin adhesion, having an adhesive layer, which can be formed without using an organic solvent, shows superior adhesion performance to the skin, and shows extremely mild irritation to the skin and stratum corneum damage. To solve the problem, the present invention provides a pressure-sensitive adhesive sheet for skin adhesion, which has a substrate and an adhesive layer laminated on the substrate, wherein the adhesive layer is obtained by curing an adhesive composition containing polyether polymer (A) having at least one alkenyl group on the terminal, compound (B) having 1-10 hydrosilyl groups in a molecule and hydrosilylation catalyst (C).
