Summary:PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesive sheet having a foam substrate with less performance deterioration when narrowed, in response to a request for narrowing the pressure sensitive adhesive sheet to be used for fixation, by a requirement of down-sizing and weight-saving of a product.SOLUTION: A pressure sensitive adhesive sheet 1 includes an adhesive layer 11 or 12 at least on one side of a foam substrate 15. In the pressure sensitive adhesive sheet 1, a relation between a 100% modulus M[N/mmsubstrate] of the pressure sensitive adhesive sheet 1 and a density D[g/cm] of the foam substrate 15 satisfies a formula 9.0≤(M/D). In the pressure sensitive adhesive sheet 1, the 100% modulus M of the pressure sensitive adhesive sheet 1 is higher than 4.0 N/mm2 substrate, and the thickness Hs of the foam substrate is 0.06-0.30 mm.SELECTED DRAWING: Figure 1
