Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a tourmaline ceramic improved in water quality improving effect and disinfecting effect, by sintering a mixture of tourmaline fine powder, ceramic powder and silver to pelletize the mixture. SOLUTION: Tourmaline fine powder having 1-15μm average fine particle in an amount of 5-50wt.% is mixed with 40-90wt.% of ceramic powder and 0.1-10wt.% of silver and pelletized by sintering at 800-950 deg.C to give a tourmaline ceramic having a shape such as spherical shape, elliptic cylindrical shape or comfit-like shape and 1-10mm average size.
