PROBLEM TO BE SOLVED: To provide an acrylic block copolymer excellent in heat resistance. SOLUTION: The acrylic block copolymer has (A) a methacrylic polymer block containing a methacrylic ester as a main component and having an acrylic ester unit and (B) an acrylic polymer block containing an acrylic ester as a main component. In the acrylic block copolymer, total weight of the acrylic ester unit in the methacrylic polymer block (A) is≥1 wt.% based on total methacrylic polymer block (A) and does not exceed total weight of methacrylic ester unit.
