Beschreibung
Zusammenfassung:	Provided are a pressure-sensitive adhesive that is suppressed from being reduced in pressure-sensitive adhesive strength at the time of its contact with an oil content or an alcohol component, and a pressure-sensitive adhesive tape including the pressure-sensitive adhesive. The pressure-sensitive adhesive of the present invention is a pressure-sensitive adhesive configured to express an adhesive property by being pressure-bonded, including: an acrylic polymer having an acid functional group; and a crystalline resin having a melting point of 25°C or more. In one embodiment, the pressure-sensitive adhesive is configured to express the adhesive property by being warmed. In one embodiment, the acrylic polymer having an acid functional group has a constituent unit "a" derived from a (meth)acrylic acid alkyl ester having a linear or branched alkyl group having 4 or more carbon atoms.
