Abstract
A foaming adhesive sheet comprising a substrate and an adhesive layer placed on at least one surface side of the substrate; wherein the adhesive layer includes a curable adhesive, and a forming agent; the adhesive layer is placed on an outermost surface; a pressure-sensitive adhesive force of the adhesive layer is 0 N/25 mm or more and 0.1 N/25 mm or less; a static friction coefficient of a surface of the adhesive layer opposite to the substrate is 0.30 or less; and a pencil hardness of a surface of the adhesive layer opposite to the substrate is F or more.
