<P>PROBLEM TO BE SOLVED: To provide an oxide-coated nickel fine particle which mitigates such a property of nickel as to be easily oxidized, can also show properties inherent in nickel such as high electric conductivity and metallic luster, and is excellent in oxidation resistance, electric conduction properties and the like, when used as a material for an electroconductive paste. <P>SOLUTION: The oxide-coated nickel fine particle comprises: a core particle (a) formed of a nickel fine particle; and a coating layer (b) formed on the surface of the core particle (a), which is formed of an oxide containing aluminum as a main ingredient, and consists of a continuous film having an average thickness of 1-20 nm. A content of aluminum is 0.07 to 0.4 wt.% with respect to a total amount of the oxide-coated nickel fine particles. <P>COPYRIGHT: (C)2012,JPO&INPIT |
