<p>PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive tape, which does not peel off easily even when exposed to a high temperature, despite being a thin pressure-sensitive adhesive tape.SOLUTION: Provided is a pressure-sensitive adhesive tape containing an adhesive layer. The adhesive layer comprises a (meth)acrylic polymer obtained by living radical polymerization and having a molecular weight distribution (Mw/Mn) of 1.05 to 2.5. The (meth)acrylic polymer contains 0.1 to 10 wt% of a component derived from a carboxyl group-containing monomer and/or 0.1 to 1 wt% of a component derived from a hydroxyl group-containing monomer, and shows weight decrease by heating at 300°C of 10 wt% or less as measured using a differential thermal analysis and thermogravimetric analysis apparatus measured at a rate of temperature increase of 5°C/min.</p> |
