<P>PROBLEM TO BE SOLVED: To provide a foamed pressure-sensitive adhesive sheet further imparted in removability and easiness of peeling the pressure-sensitive adhesive sheet in consideration of environmental load such as recyclability while keeping adhesive force, followability and flexibility. <P>SOLUTION: The foamed pressure-sensitive adhesive sheet is provided with a layer of a pressure-sensitive adhesive composition on at least one surface of an olefinic resin foamed body having an average air bubble diameter of 0.02-0.2 mm, apparent density of 30-100 kg/m<SP POS="POST">3</SP>and compressive stress at 50% compression of 10-90 KPa, the adhesive force of the foamed pressure-sensitive adhesive sheet is less than 5.0 N/20 mm width by a 90 degree peeling test, and the storage modulus (G') of the pressure-sensitive adhesive composition at a room temperature is less than 20 N/cm<SP POS="POST">2</SP>. <P>COPYRIGHT: (C)2012,JPO&INPIT |
