[PROBLEMS] To provide an antibacterial and antifungal agent having excellent heat resistance and excellent dispersibility in resins, ceramics, metals, solvents and the like. By reacting inorganic particles with a compound having a polymerization initiating ability or a compound having a polymerizable ethylenically unsaturated group, a functional group having a polymerization initiating ability or a polymerizable ethylenically unsaturated group is produced. Inorganic particles having. By polymerizing a monomer having a functional group that can be converted into a cationic group on the inorganic particles, the functional group in the polymer is converted into a cationic group, and then subjected to a salt exchange reaction with a super strong acid. An antibacterial and antifungal agent comprising a polymer having a super strong acid anion and a cationic group grafted to inorganic particles. [Selection figure] None |
