Abstract

Provided are a pressure sensitive adhesive sheet including, on a substrate, a resin layer containing a resin which is a resin layer containing a resin part (X) containing a resin as a main component and a particle part (Y) consisting of fine particles, at least a surface (α) of the resin layer on the side opposite to the side thereof on which the substrate is provided, having pressure sensitive adhesiveness, wherein a bending stress coefficient k in the MD direction of the substrate is 20 N·mm or less, a 10% elongation strength in the MD direction thereof is 260 N/15 mm or less, and concave portions satisfying specified requirements are included on the surface (α) of the resin layer; and a method for producing the pressure sensitive adhesive sheet.
