Abstract
To obtain metal oxide layer having a reactiveness to electromagnetic wave whose wave length is longer than that of ultraviolet rays, for example, visible radiation or the like. A metal oxide layer is a layer of a stable metal oxide, for example, TiO, ZnO, WO, SnO, ZrO or the like obtained by melting and adhering metal powder for forming a layer of titanium (Ti), zinc (Zn), wolfram (W), stannum (Sn) and zirconium (Zr) or the like on a surface of a product to be treated comprising of a metal, ceramics or a mixture of them by injecting the metal powder with high speed by dint of using a compressed air and has oxygen deficit tilting structure wherein bonding quantity of oxygen is decreased as goes from the surface to the inside gradually.
