A hydrogen generation apparatus is constituted of a treated-substance container, which has a hydrogen discharge port for activating a treated substance; and at least one plate-form activation structural body, which is provided within the treated-substance container vertically thereto. The plate-form activation structural body is a structural body that arranges particles composed of any of a single constituent element, which is selected from a group comprising silicon, titanium, nickel, and samarium, and fluorocarbon at positions that amplify unique wave energy in each the element and the fluorocarbon, and which structural body has an energy concentration field between the particles within the treated-substance container, wherein gases containing hydrogen are generated by any of the treated substance within the treated-substance container staying in and passing through the energy concentration field. The hydrogen generation apparatus can generate hydrogen with less energy and achieve space saving.
