PROBLEM TO BE SOLVED: To provide copper powder which has more excellent oxidation resistance, and has excellent conductivity as well. SOLUTION: The surface of copper grains are coated with a sulfur compound such as acid thiols, e.g., mercaptopropionic acid, mercaptoacetic acid, thiodipropionic acid, mercaptosuccinic acid and thioacetic acid, and a silicon oxide. The copper powder is produced by reacting a copper compound and a reducing agent in the presence of a sulfur compound to obtain copper grains coated with the sulfur compound, and next subjecting a silicon compound such as alkoxysilane to hydrolysis in the presence of the obtained copper grains.
