PROBLEM TO BE SOLVED: To provide an antifungal agent that can manifest excellent antifungal properties, even when the agent is kneaded together with a resin, without discoloration of the resin, in a short time after it is applied, even in the case of a small amount of the agent applied. SOLUTION: In this antifungal agent, the diffusion layers of silver are formed on the surface of zinc oxide fine particles with an average particle size of <=1μm in scattered dots and zinc oxide is exposed on the surface of the fine particles. The fine particles of zinc oxide are covered on their surfaces with 1-10 mass % of silver in the scattered dot form, then they are heated at 400-800 deg.C in an inert gas atmosphere whereby the silver is diffused on the zinc oxide fine particles to form the diffused silver layer thereon in the scattered dot form.
