PROBLEM TO BE SOLVED: To provide pressure-sensitive adhesive tapes for temporarily fixing parts which have high adhesion in temporarily fixing parts and can easily be released in taking out the parts and, in addition, do not stain the parts. SOLUTION: Pressure-sensitive adhesive tapes for temporarily fixing parts have a pressure-sensitive adhesive layer on one side or both sides of a base film, and the pressure-sensitive adhesive layer is formed of an adhesive composition containing a pressure-sensitive adhesive and a side chain crystallizable polymer. The side chain crystallizable polymer can be obtained from a monomer mixture containing 40-70 wt.% (meth)acrylic 1-6C alkyl ester, 2-10 wt.% carboxyl group-containing ethylenically unsaturated monomer, and 20-50 wt.% (meth) acrylic >=16C alkyl ester, and has a weight average molecular weight of 3,000-25,000.
