A structural body which comprises a base and a microrelief structure layer having a microrelief structure. The microrelief structure layer is laminated on the base so as to form the surface layer of this structural body, and the microrelief structure layer has at least one physical property selected from the group consisting of (A) and (B) described below. (A) The elastic modulus at 25°C is 50 MPa or more, and the elastic modulus at 80°C is 30 MPa or less. (B) The tensile elongation at break at 80°C is from 20% to 100% (inclusive).
