Abstract

Provided is a PSA sheet that achieves both bonding reliability at a high temperature and reduction of outgassing. The PSA sheet provided by this invention comprises a substrate layer and a PSA layer provided to one face of the substrate layer. The PSA sheet exhibits a 180° peel strength of 1 N/20 mm or greater to stainless steel at 60° C. It has an amount of thermally released gas of 10 μg/cmor less, determined at 130° C. for 30 minutes by GC-MS.
