The invention relates to a drinking electrolytic water apparatus using a bottled water as an unpurified water by which high preference water, such as the water having anti-oxidation, high reducibility and containing hydrogen, etc., is generated. The apparatus is composed of a bottle(1), a pump(7), an electrolytic apparatus(3), a mixed channel selecting valve(4), a water storage tank(5) and a water taking valve(6). The bottle is used to supply the unpurified water, the pump is used to pump the unpurified water in a filter apparatus(2), and the electrolytic apparatus(3) is equipped with an electrolytic mechanism carrying out electrolysis on the filtered unpurified water; the mixed channel selecting valve(4) is used to mix the water discharged from the filter apparatus with an electrolysis water or mix the water discharged from the filter apparatus with the unpurified water before filtering, the water storage tank(5) is used to store the electrolysis water and keep the electrolysis water in a cooling state, and the water taking valve(6) is used to obtain the water in the water storage tank(5).
