To provide a method of producing hydrogen-containing drinking water, which is appropriate for production on a large scale, small in a fluctuation of hydrogen dissolved amounts, and high in a hydrogen concentration.
The method comprises dissolving hydrogen into raw water by feeding the raw water to a raw water streaming part of a hydrogen gas dissolving module which is partitioned into the raw water streaming part and a hydrogen gas streaming part with a gas-permeable membrane composed of a hydrophobic material while feeding pressurized hydrogen gas to the hydrogen gas streaming part of the hydrogen gas dissolving module, thereafter filling the raw water dissolved with hydrogen gas ejected from the raw water streaming part of the hydrogen gas dissolving module into a container, sealing it, and sterilizing it.
