摘要: A foam substrate-attached adhesive sheet or tape comprising a substrate having formed thereon a layer of a pressure-sensitive adhesive, wherein the substrate is a foam elastomer having a breaking elongation of at least 800% and an apparent 800% modulus of from 1.0 to 15 kg/cm.sup.2 in a tensile test of 23.degree. C., and a breaking elongation of at least 400% and an apparent 400% modulus of from 2.0 to 60 kg/cm.sup.2 in a tensile test of -30.degree. C.
