Abstract
The present invention aims to provide an adhesive tape achieving both excellent adhesion and excellent holding power. Provided is an adhesive tape including an adhesive layer, the adhesive layer having scattering peaks in a scattering vector q range from 0.05 nm−1 to 1.0 nm−1 in small-angle X-ray scattering (SAXS) measurements at 23° C. and 100° C., and the adhesive layer having peaks of a loss tangent tan δ as determined by dynamic viscoelasticity measurement at a measurement frequency of 1 Hz, a temperature of a peak observed at the highest temperature among the peaks being 45° C. or lower.
