Abstract: Provided is a laminate sheet in which a first sheet, a PSA layer and a second sheet are laminated in this order. Of the first and second sheets, at least one is a release liner having a release face on the side facing the PSA layer. The PSA layer has a thickness of 200 μm or greater. The first sheet has a tensile modulus of 1000 MPa or greater and the second sheet has a tensile modulus of 500 MPa or less.

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/cm2 or less, determined at 130° C. for 30 minutes by GC-MS.
