PROBLEM TO BE SOLVED: To solve a problem wherein in the case of using an acrylic block copolymer as an adhesive and a polyolefin-based polymer or a modified polyolefin-based polymer as a substrate material, since the close adhesion of the acrylic block copolymer to the substrate material is low, on re-peeling it as the adhesive from an adhered body, it is peeled off at the boundary of the substrate material with the acrylic block copolymer and the acrylic block copolymer remains on the adhered material (paste residues). SOLUTION: This adhesive includes (A) 1 to 99 wt.% of an acrylic block copolymer consisting of (a) a methacrylic polymer block and (b) an acrylic copolymer block, and (B) 99 to 1 wt.% of a modified olefinic polymer.
