PROBLEM TO BE SOLVED: To obtain a surfactant with high safety capable of obtaining excellent washing effect and anti-bacterial effect. SOLUTION: The surfactant is constituted so as to include an anti-bacterial grain 1 obtained by depositing an inorganic anti-bacterial powder 3 of Ag-A type zeolite (silver ion exchange A type zeolite) having an average particle diameter of about 2μm, a specific gravity of 2.1-2.2 and an ion exchange ratio of 4.5% on a surface of a granular base material 2. Further, the base material comprises a thermoplastic resin, and the inorganic anti-bacterial powder is directly deposited at melting of the surface of the base material. COPYRIGHT: (C)2008,JPO&INPIT
