The present invention relates to a hydrogen water and sterilizing water generator that uses electrolysis to generate hydrogen water and sterilizing water. The hydrogen water and sterilizing water generator of the present invention is provided with an electrolysis section having at least two electrodes and electrolyzing water, an introduction path for introducing water into the electrolysis section, and a switching mechanism for switching the positive and negative of the electrodes. The mechanism switches the positive and negative of the aforementioned electrodes during electrolysis, and hydrogen water and sterilizing water are produced in the same path.本發明係關於一種利用電解而產生氫水及殺菌水之氫水及殺菌水產生裝置。本發明之氫水及殺菌水產生裝置具備:具有至少2個電極且將水予以電解之電解部、朝前述電解部導入水之導入路徑、及切換前述電極之正負之切換機構,藉由前述切換機構切換電解時之前述電極之正負,而在同一路徑中產生氫水與殺菌水。
