PROBLEM TO BE SOLVED: To provide a tacky adhesive sheet which has a short aging time from when a tacky adhesive composition is coated in a sheet-like shape till when processing such as cutting can be performed on the sheet without difficulty, and which has excellent processability.SOLUTION: A tacky adhesive sheet is formed into the sheet-like shape from a tacky adhesive composition containing: an acrylic resin (A) being a copolymer obtained from a monomer mixture containing 62-99.9 wt.% of the (meth)acrylate (A-1) shown by formula (I) and 0.1-8 wt.% of a (meth)acrylic monomer (A-2) having a hydroxyl group; a cross-linking agent (B); and a (meth)acrylate monomer (C) containing a carboxyl group, which is shown by formula (II). In formula (I) and formula (II), Rand Rare each a hydrogen atom or a methyl group; Ris a ≤14C alkyl group; and A is a 2-4C bivalent organic group. |
