PROBLEM TO BE SOLVED: To provide an electrode structure of hypochlorite generator and hypochlorite generator capable of generating and vaporizing hypochlorite, safely by individual, because when generating hypochlorite by electrolysis at a place there are people, due to discharge of chlorine gas generated on a positive electrode to ambient air, discomfort of throat such as a sore throat occurs.SOLUTION: Chlorine gas generated on a positive electrode is made remain in an electrolytic cell or alkaline tank gas phase, and then the chlorine gas is adsorbed in an electrolytic solution again, for preventing discharge of the chlorine gas to ambient air, and/or irritation of the chlorine gas or hypochlorous acid gas in the ambient gas is stabilized by humidification of the ambient air.【課題】人のいるところで電解により次亜塩素酸生成を行うと、陽電極で発生する塩素ガスの大気中への放出により、喉のいがらっぽさなどの違和感があった。個人が安全に次亜塩素酸生成・気化を行える、次亜塩素酸生成装置の電極構造体及び次亜塩素酸生成装置を提供する。【解決手段】陽電極で発生する塩素ガスを電解槽やアルカリ槽気相内に滞留させ電解液に再吸収させ大気への放出を防止し、または/および大気の加湿により大気中での塩素ガスや次亜塩素酸ガスの刺激性を安定化する。【選択図】図2
