To provide a chemical sensor and an electrode recycling method that can be continuously used and can be applied to environmental monitoring.SOLUTION: A chemical sensor 1 comprises: a recycling unit 2 that has a flow channel 21, a liquid storage unit 22, an electrolytic film 23, a first electrode 24, and a second electrode 25; voltage application means 3 that applies a voltage to the two electrodes; and detection means 4 that detects a substance to be measured 110 attached to the first electrode 24. The flow channel 21 and the liquid storage unit 22 are joined to each other with the electrolytic film 23 therebetween. The flow channel 21 is a flow channel in which a sample solution 120 including the substance to be measured 110 is caused to flow, and the liquid storage unit 22 is a container or a flow channel that stores an ion receiving liquid 130 receiving H+ or OH- included in the sample solution 120 in the flow channel 21.SELECTED DRAWING: Figure 1 【課題】連続的に使用でき環境モニタリングに適用できる化学センサ及び電極の再生方法を提供する。【解決手段】流路２１、液体収容部２２、電解膜２３、第１電極２４及び第２電極２５を有する再生部２と、２つの電極に電圧を印加する電圧印加手段３と、第１電極２４に付着した測定対象物質１１０を検出する検出手段４とを備え、流路２１と液体収容部２２は電解膜２３を介して接合し、流路２１は測定対象物質１１０を含む試料溶液１２０を流す流路、液体収容部２２は流路２１内の試料溶液１２０に含まれるＨ＋又はＯＨ－を受容するイオン受容液体１３０を収容する容器又は流路である、化学センサ１。【選択図】図１
