PROBLEM TO BE SOLVED: To provide a water purifying agent for removing odor of chlorine or bleaching powder, etc., adding a mineral component to water, having a sterilizing work and prolonging the exchange period, and a manufacturing method for manufacturing a more hardened purifying agent. SOLUTION: Activated carbon having a 20-50% weight ratio, kaolin having a 30-60% weight ratio, and at least one among dolomite, tourmaline, granite porphyry, zeolite type quartz diorite, and diatom earth each having a 15-45% weight ratio, and silver having a >=0.05% weight ratio and/or titanium having a >=0.1% weight ratio are mixed under vacuum. The mixed product is molded into a specified shape and is heated at 1100-1250 deg.C under an oxygen-free condition. Thus the water purifying agent for removing chlorine or bleaching powder from water and adding a mineral component to eater and providing a sterilizing work, is manufactured. Also, by mixing under vacuum and then firing at a specified temperature under an oxygen-free condition, the much hardened water purifying agent can be manufactured.
