The problem to be solved by the present invention is that the adhesive sheet is peeled with time regardless of whether the shape of the substrate to which the adhesive sheet is attached is a flat part or a curved part such as an R part or an inverted R part. It is an object to provide a pressure-sensitive adhesive having a level of excellent adhesive strength that does not cause odor. The present invention relates to an acrylic polymer (A) having a nitrogen atom-containing group having a weight average molecular weight of 1,000 to 50,000, an acrylic polymer (B) having a weight average molecular weight of 500,000 or more, and a solvent ( C), the acrylic polymer (A) does not have a carboxyl group, and the acrylic polymer (B) does not have a carboxyl group and a nitrogen atom-containing group. The present invention relates to a pressure-sensitive adhesive and a pressure-sensitive adhesive sheet using the same. [Selection figure] None |
