PROBLEM TO BE SOLVED: To provide a powder having neither water discoloration problem of silver-based zeolite antibacterial agent nor lack of water resistance and heat resistance of quaternary ammonium antibacterial agent, and sustained release of antibacterial component, which has high water resistance, heat resistance and little or no tendency to discoloration To provide a body. An antibacterial agent characterized by being a faujasite type zeolite into which tetramethylammonium ions are introduced by ion exchange. The faujasite type zeolite is an X type or Y type zeolite. Zinc ions, copper ions, and silver ions are further used as ion-exchangeable ions. [Selection figure] None |
