Abstract

A method of producing a roll-shaped body comprises: obtaining an adhesive agent sheet having an embossed shape at both surfaces thereof by imparting an embossed shape on both surfaces of an adhesive agent sheet containing a thermoplastic resin as a main component; overlapping a protective sheet having releasability from the adhesive agent sheet to at least one surface of the adhesive agent sheet having the embossed shape at both surfaces thereof; and obtaining the roll-shaped body by wounding the adhesive agent sheet having the embossed shape at both surfaces thereof and the protective sheet that are overlapped facing one another.
