(57) [Summary] [Problem] When bonding an abrasive to a polishing platen, position adjustment is easy, the adhesive strength does not decrease from a low temperature range to a high temperature range, the abrasive does not peel off during polishing, and after polishing is completed. Provides a double-sided tape for fixing abrasives, which can remove abrasives with an appropriate force. SOLUTION: With respect to 100 parts by weight of an acrylic polymer, Softening point is 100 ° C or higher (preferably 120 ° C or higher) 17 1 ° C. or less and a tackifying resin (preferably a polymerized rosin ester) which is incompatible with the acrylic polymer An abrasive-fixing tape comprising an acrylic pressure-sensitive adhesive layer containing 0 parts by weight or more and 35 parts by weight or less provided on both surfaces of a substrate. |
