PROBLEM TO BE SOLVED: To provide a method and apparatus for manufacturing purified water for medicines for efficiently sterilize an apparatus for manufacturing purified water with hot water, reducing the cost for sterilization by reducing the volume of blow water to the outside of the system and reducing the volume of water and steam to be used and can suppress the proliferation of living microorganisms by eliminating a retention part. SOLUTION: In sterilizing the inside of the system by hot water before starting manufacture of the purified water from raw water with the system successively provided with a reverse osmosis membrane apparatus and an electric regeneration type water purifying apparatus, the method and apparatus for manufacturing the purified water for medicines manufacture the purified water by passing the substantially non-heated raw water through the reverse osmosis membrane apparatus and the electric regeneration type water purifying apparatus in this order, storing the treated water thereof as the treated raw water, circulating the treated raw water in the inside of the system while heating the same to sterilize the inside of the system, and successively passing the raw water through the reverse osmosis membrane apparatus and the electric regeneration type water purifying apparatus after the sterilization.
