(57) [Summary] [PROBLEMS] To remove dioxins, chlorine compounds, nitrate compounds, nitrogen compounds and organic compounds contained in drinking water such as tap water and well water by oxidative decomposition treatment using a photocatalyst, and at the same time to be contained in drinking water. Provided is a water purifier that can sterilize bacteria and provide more purified drinking water. SOLUTION: In a water purifier having a cartridge 2 for removing dust and chlorine in drinking water W and an electrolyzed water generating device 3 for converting drinking water W to alkaline ionized water, the cartridge 2 and the electrolyzed water generating device 3 In the meantime, a photocatalyst device 1 that irradiates ultraviolet rays to the titanium dioxide 1c to generate a catalytic action is provided, and the drinking water W is passed through the photocatalyst device 1 and sterilized by ozone that generates bacteria in the drinking water W, The generated ozone is decomposed and rendered harmless by the electrolyzed water generator 3. |
