PROBLEM TO BE SOLVED: To provide an oxide-coated copper fine particle which mitigates such a property of metal as to be easily oxidized, can also show properties such as high electric conduction properties and metallic luster that metal originally has, and is excellent in oxidation resistance, electric conduction properties and the like, when used as a material for an electroconductive paste, and to provide a method for effectively producing the same at a low cost. SOLUTION: The oxide-coated copper fine particle comprises: a core particle (a) formed of a copper fine particle; and a coating layer (b) formed on the surface of the core particle (a), which is formed of an oxide that contains aluminum as a main ingredient. A content of the above aluminum is 0.1 to 0.8 wt.% with respect to a total amount of the oxide-coated copper fine particles. COPYRIGHT: (C)2008,JPO&INPIT
