PROBLEM TO BE SOLVED: To provide a hydrogen water feeding device capable of visually confirming that hydrogen is actually contained in provided hydrogen water.SOLUTION: In a hydrogen water feeding device (1) to feed hydrogen water where hydrogen is contained in city water,: a pressure reducing means (3) is located between a hydrogen water feeding source (2) to feed the hydrogen water and an opening and closing valve (4); the hydrogen water including fine hydrogen bubbles is provided from the opening and closing valve (4) by feeding the hydrogen water after reducing pressure by the pressure reducing means (3); and in particular, the hydrogen water is produced by dissolving hydrogen in city water in a saturated state at higher pressure than atmospheric pressure and the pressure of the hydrogen water is reduced to be lower than atmospheric pressure by the pressure reducing means (3). |
