높은 표면 경도와 가요성을 양립한 적층체를 제공한다. 지지 기재 상에 표면층이 적층된 적층체이며, 상기 표면층의 두께 방향의 탄성률 분포에 있어서, 탄성률이 지지 기재의 탄성률보다도 높은 극댓값과 탄성률이 지지 기재의 탄성률보다도 낮은 극솟값이 존재하고, 상기 표면층에 있어서의 지지 기재와의 계면측의 탄성률과 최표면측의 탄성률이, 모두 지지 기재의 탄성률보다도 높은 것을 특징으로 하는 적층체. Provided is a layered body in which flexibility and high surface hardness are both obtained at the same time. A layered body in which a surface layer is layered on a supporting substrate, the layered body characterized in that a maximum value at which the elastic modulus of the surface layer is higher than the elastic modulus of the supporting substrate and a minimum value at which the elastic modulus of the surface layer is lower than the elastic modulus of the supporting substrate are present in the elastic modulus distribution in the thickness direction of the surface layer, and the elastic modulus on the interface side of the surface layer with the supporting substrate and the elastic modulus of the outermost surface side of the surface layer are both higher than the elastic modulus of the supporting substrate.
