Electrolytic solution generator

An electrolytic solution generator comprising:

• an electrolyzing unit having a stacked structure in which a conductive film is interposed between a cathode and an anode, the electrolyzing unit electrolyzing a liquid;
• and
• a housing in which the electrolyzing unit is disposed,
• the housing includes a channel, the channel having an inlet into which a liquid to be supplied to the electrolyzing unit flows and an outlet from which an electrolytic solution generated by the electrolyzing unit flows out, the channel causing a liquid to flow in a liquid-flow direction intersecting a stacking direction of the stacked structure and a widthwise direction of the housing,
• the electrolyzing unit includes a groove, the groove being open to the channel, at least a part of an interface between the conductive film and the cathode and an interface between the conductive film and the anode being exposed to the groove,
• the channel includes a side face extending from an inlet side to an outlet side in the flow direction,
• a space is disposed at least in one of a position between an outer periphery of the cathode and the side face of the channel in the widthwise direction, or a position between an outer periphery of the anode and the side face of the channel in the widthwise direction, and
• the space is a gap larger than a manufacturing tolerance.
