Abstract

Electrolytic liquid generating device (1) includes laminated body (41) in which conductive film (46) is laminated to be interposed between mutually adjacent electrodes (44, 45), and electrolytic part (40) which electrolyzes liquid. Furthermore, electrolytic liquid generating device (1) includes a passage having inflow port (71) in which liquid to be provided to electrolytic part (40) flows and outflow port (72) from which electrolytic liquid generated in electrolytic part (40) flows out. The passage is formed such that liquid flowing direction (X) crosses laminated direction (Z) of laminated body (41).
