An optical double-sided pressure-sensitive adhesive sheet having excellent reworkability, step-absorbing property and anti-foaming peelability is provided. The optical double-sided pressure-sensitive adhesive sheet of the present invention has an acrylic pressure-sensitive adhesive layer containing an acrylic polymer (X), and the total amount (100% by weight) of monomer components forming the acrylic polymer (X). The content of the (meth) acrylic acid alkyl ester having a linear or branched alkyl group having 1 to 14 carbon atoms is 50 to 100% by weight, and the content of the polar group-containing monomer is 0 to 15.0% by weight, and the gel fraction of the acrylic pressure-sensitive adhesive layer is 20 to 74% by weight.
