Disclosed are a cuprous oxide powder having a low carbon content and a low chlorine content and a method for producing the same. In a method for producing cuprous oxide powder in which an alkali solution and a reducing agent solution are added to an aqueous solution containing divalent copper ions to reduce and precipitate cuprous oxide particles, the alkali solution does not contain carbon and chlorine. By using an alkaline solution and a reducing agent solution containing no carbon and chlorine as the reducing agent solution, the 50% particle size is 0.05 to 1.0 μm and the carbon content is 0.1% by mass. Hereinafter, a cuprous oxide powder having a chlorine content of less than 0.01% by mass and a mixture of a spherical shape, a substantially spherical shape, and at least one of a hexahedral shape and a scale shape is produced.
