An aluminum salt-containing resin powder of the present invention includes: at lest one matrix resin component selected from regenerated collagen, polyvinyl alcohol and carboxymethyl cellulose; and an aluminum salt. The aluminum salt is chemically bonded to the matrix resin component, and the resultant is powdered. A resin composition of the present invention includes 0.1 wt % or more and 80 wt % or less of the aluminum salt-containing resin powder and 20 wt % or more and 99.9 wt % or less of a resin other than the aluminum salt-containing resin. Thus, the present invention provides an aluminum salt-containing resin powder having a high phosphorus adsorption property, a high antibacterial property and a high antifungal property, and a resin composition containing the aluminum salt-containing resin powder. |
