Abstract: Provided is a roll-shaped body that includes an adhesive agent sheet excelling in terms of low hygroscopicity, light resistance, transparency, and flexibility and that can prevent blocking of the adhesive agent sheet even upon temporary exposure to a high-temperature condition during storage or transport. The roll-shaped body includes an adhesive agent sheet containing a thermoplastic resin as a main component and having an embossed shape at both surfaces thereof. In the roll-shaped body, at least one surface of the adhesive agent sheet and a protective sheet having releasability from the adhesive agent sheet are overlapped facing one another and are wound up.
