A method for continuously producing hydrogen-containing water for beverages, comprising (A) a degassing step, (B) a hydrogen dissolving step, (C) a filling step, and (D) a sealing step, and the degassing step A pressure is applied to the water flow path from the purified water supplied to the hydrogen-containing water injected into the packaging container in the filling step, and the filling step is a device for filling the hydrogen-containing water under pressure. A preparation stage for supplying the inside of the packaging container, a degassing stage for removing the gas inside the packaging container after the packaging container is connected to the filling device, and an injection stage for directly injecting the hydrogen-containing water under pressure into the packaging container And a discharging step of introducing pressurized air into the filling device and discharging the hydrogen-containing water remaining in the filling device into the packaging container, and then immediately sealing the container when the packaging container and the filling device are disconnected. The manufacturing method which consists of a process which transfers to a process (D).連続して飲料用水素含有水を製造する方法であって、（Ａ）脱気工程と（Ｂ）水素溶解工程と（Ｃ）充填工程と（Ｄ）密封工程とを含み、また前記脱気工程に供給される浄化水から前記充填工程にて包装容器に注入される水素含有水までの水流路には圧力が負荷されてなり、前記充填工程は、圧力が負荷された水素含有水を充填装置内に供給する準備段階と、包装容器を充填装置と接続した後、包装容器の内部の気体を除去する脱気段階と、圧力が負荷された水素含有水を包装容器内に直接注入する注入段階と、加圧空気を充填装置内に導入して、充填装置内に残る水素含有水を包装容器内に排出する排出段階とを含み、その後包装容器と充填装置の接続を解いたとき直ちに前記密封工程（Ｄ）に移行する工程からなる、製造方法。
