[Problem] To provide an electrolysis-type hydrogen gas suction tool which is portable, and capable of supplying a prescribed amount of hydrogen gas with ease. [Solution] This electrolysis-type hydrogen gas suction tool is provided with: a main body cover member provided with a battery, a control board for controlling the power supply from the battery, and a pair of positive and negative electrodes through which the passage of electric current with respect to a positive electrode and a negative electrode of the battery is allowed or interrupted by the control board； an electrolysis tank which is detachably attached to the main body cover member, has, inserted therein in a lower part thereof in an attached state, the pair of positive and negative electrodes, and is capable of storing water； a nozzle part provided with a through hole； and a mixing part provided with a flow path which fluidly connects the nozzle part and the upper end of the electrolysis tank. The electrolysis tank is formed from an upper part and the lower part of which the insides are fluidly connected, and which are integrally moulded. The width from a side part of the upper part at one side to a side part at the other side narrows towards the boundary between the upper part and the lower part. A partition plate is provided extending towards the one side from a position in the vicinity of the boundary at the other side.
