PROBLEM TO BE SOLVED: To provide a laminate material in which a metal layer is observed as black without providing a blackened layer separately from a metal layer, when the laminate material is observed from a transparent support side, the laminate material with improved productivity and durability.SOLUTION: A laminate material includes a transparent support and a metal layer disposed on the transparent support. A surface of the transparent support covered with the metal layer is a rugged surface formed with a fine ridge group including a unit ridge extending in one direction. The spacing of adjacent unit ridges in the ridge group is equal to or narrower than the minimum wavelength of a visible ray band. 【課題】金属層とは別途に黒化層を設けることなく、透明支持体の側から積層材を観察した場合に金属層が黒色に観察される積層材であって、生産性及び耐久性の面で改良された積層材を提供する。【解決手段】透明支持体と、前記透明支持体上に設けられた金属層と、を備え、前記透明支持体の前記金属層で覆われている面は、一方向に延在する単位凸条からなる微細凸条群により形成された凹凸面となっており、前記微細凸条群の隣接する単位凸条間隔は、可視光線帯域の最短波長以下である。【選択図】図１
