摘要：The problem of the present invention is to provide an adhesive tape of a foambase material capable of maintaining the original physical property even when thematerial is exposed to a high temperature and can be maintained even if it is exposed to aroom temperature even when it is returned to room temperature. The present inventioncomprisesAn adhesive tape having an adhesive layer on at least one side of a foamsubstrate having a pseudo skin layer on both surfacesThe foam substrate has a 25%compressive strength of 20 to 170 kPaThe tensile modulus at 100 ° C. in the flowdirection at 23 ° C. is E1.The ratio E2 \\/ E1 when the tensile modulus of the tensiledirection in the flow direction of 120% at 120 ° C. is E2 isThe tensile modulus of width100% in the width direction of 23% at 23 ° C. is E1 '.The present invention relates to anadhesive tape characterized in that the ratio E2 ′ \\/ E1 ′ when the tensile modulus of thetensile direction in the width direction of 100% at 120 ° C. is E2 ′ is 0.1 or more.Noselection
