A heat-resistant adhesive sheet for semiconductor testing, used in a performance test while semiconductor chips are heated includes: a base material; and an adhesive layer provided on the base material, the base material having a thermal shrinkage of lower than 1% when being heated at 150 degrees Celsius for 30 minutes and a linear expansion coefficient of equal to or lower than 5.0×10−5 at 60 to 150 degrees Celsius, and the adhesive layer containing a (meth)acrylic acid ester copolymer, a photopolymerizable compound, a polyfunctional isocyanate curing agent, and photoinitiator. The adhesive layer contains 5 to 200 parts by mass of the photopolymerizable compound, 0.5 to 20 parts by mass of the polyfunctional isocyanate curing agent, and 0.1 to 20 parts by mass of the photoinitiator, with respect to 100 parts by mass of the(meth)acrylic acid ester copolymer. The adhesive layer is free of tackifying resin. |
