PROBLEM TO BE SOLVED: To provide a new coating capable of improving scratch resistance, weather resistance and adhesion to a substrate furthermore in comparison with a conventional coating, and containing cuprous oxide; and to provide a manufacture method thereof.SOLUTION: A thermal spray material formed by adding powder of copper oxide to powder of an Al alloy, a Zn alloy, a Ni alloy, an Fe alloy or an amorphous alloy is sprayed, and the copper oxide is reduced to cuprous oxide in the thermal spray material by spraying, to thereby manufacture a metal sprayed coating containing cuprous oxide on a substrate.SELECTED DRAWING: Figure 1 【課題】従来の塗膜に比べ、耐傷付き性、耐候性及び基材に対する密着性を向上させ得る、亜酸化銅を含有する新たな皮膜及びその作製方法を提供する。【解決手段】Ａｌ合金、Ｚｎ合金、Ｎｉ合金、Ｆｅ合金又はアモルファス合金の粉末に酸化銅の粉末を添加した溶射材料を溶射し、この溶射により溶射材料中の酸化銅を亜酸化銅に還元して基材上に亜酸化銅を含有する金属溶射皮膜を作製する。【選択図】図１
