Zusammenfassung:	A PSA sheet 40 including a PSA layer formed from an aqueous PSA composition and having adequate bonding workability with respect to elastic foams is provided. When this PSA sheet 40 is pressure-bonded to a flexible urethane foam 42 of 10 mm in thickness under conditions where the urethane foam 42 is compressed to a thickness of 5 mm, the 180° peel adhesive strength 30 minutes after the pressure-bonding is 1.5 N/20 mm or greater. ECS (gray), a product from Inoac Corporation, is used as the flexible urethane foam 42.
