A cobalt salt of a monovalent acid, for instance, an aqueous solution of cobalt chloride, is added to a metal salt of a resin acid, for instance, aqueous solution of sodium gum rosinate at a temperature of not more than 50° C. to proceed the metathetical reaction, thereby producing the cobalt resinate. The resulting metal salt is precipitated without performing extraction with a solvent and separated through mechanical way such as a centrifugal separation or filter press. The resulting cobalt resinate was washed with water, and dried at a temperature of not more than 60° C.
