(57) [Summary] [PROBLEMS] To provide a material which has not only an antibacterial action but also a deodorant action and has good handleability. SOLUTION: An outer shell layer 2 is formed on the surface of sodium polyacrylate particles 1. In the outer shell layer 2, titanium dioxide particles 3 are dispersed, and a large number of fine holes 4 are formed. The outer shell layer 2 is made of polystyrene, methyl methacrylate polymer, or the like. In addition, the sodium polyacrylate particles 1 include a metal ion antibacterial agent, It preferably contains a silver ion antibacterial agent, a copper ion antibacterial agent and the like. The sodium polyacrylate particles 1 can be leached out of the fine holes 4 as ions. |
