The present invention relates to a skin pressure-sensitive adhesive that has good adhesiveness and re-peelability to human skin, has no skin keratin when peeling, and has low irritation to the skin, and a tape using the same Or to provide a sheet. The skin adhesive of the present invention is composed of (a) an olefin macromonomer and a vinyl monomer, and its molecular weight (in terms of polystyrene by gel permeation chromatogram (GPC)) has a bimodal distribution (post-crosslinked). In the case, distribution of molecular weight before crosslinking) 100 parts by weight of the copolymer, and (b) a softening agent 20 to 20 that is compatible with the copolymer and has a boiling point of 250 ° C. or higher at room temperature or in liquid or paste form It is characterized by comprising 250 parts by weight (however, if it exceeds 80 parts by weight, it is essential that the copolymer be post-crosslinked). |
