Abstract

An electrolytic liquid generation device according to the present disclosure includes an electrolytic part and a housing in which the electrolytic part is disposed. The electrolytic part has a laminate including mutually adjacent electrodes and a conductive film interposed between the electrodes. The electrolytic part electrolyzes a liquid. The housing includes an electrode case having a recess with an opening to enable insertion of the electrolytic part through the opening and to contain the electrolytic part in the recess, and an electrode case lid to cover the opening of the electrode case. The electrolytic part is contained in the recess such that lamination direction Z of the laminate is substantially aligned with a direction in which the opening opens. This configuration provides an electrolytic liquid generation device that can be built with improved facility.
