【Task】 To provide a pressure-sensitive adhesive which exhibits excellent adhesive strength to an oil-adhered adherend, has removability, and has excellent tack and water resistance. [Solution] An adhesive containing an acrylic copolymer (A), an isocyanate curing agent (B), a tackifier (C) and a release agent (D), wherein the acrylic copolymer (A) is a copolymer. Carboxyl group-containing monomer (a1) is contained as a monomer unit constituting the coalescing, and the compounding amount of the isocyanate curing agent (B) is 0.3 parts by mass or more based on 100 parts by mass of the acrylic copolymer (A). An adhesive containing 10 parts by mass or less, wherein the tackifier (C) contains a terpene resin and / or a petroleum resin, and the release agent (D) contains a compound having a molecular weight of 250 to 1,000.
