Zusammenfassung:	To provide a corrosion sensor capable of measuring a corrosion state of a steel material in a concrete structure in a short time and monitoring it for a long time.SOLUTION: A corrosion sensor 10 for detecting a corrosion state of a steel material in a concrete structure 1 includes: an electric wire 3a electrically connected with the steel material; an electrode 30 arranged on a surface of the concrete structure; and a voltage detecting unit 60 for detecting a voltage between the electrode and the electric wire. The electrode includes a hot melt electrode 50 containing hot melt resin in which conductive filler is dispersed.SELECTED DRAWING: Figure 2 【課題】コンクリート構造物中の鋼材の腐食状態を短時間で測定できると共に、長期的に監視可能な腐食センサを提供すること。【解決手段】コンクリート構造物１中の鋼材の腐食状態を検出する腐食センサ１０であって、前記鋼材に電気的に接続される電線３ａと、前記コンクリート構造物の表面に配置される電極３０と、前記電極と前記電線との間の電圧を検出する電圧検出部６０とを備え、前記電極が、導電性フィラーが分散されたホットメルト樹脂を含むホットメルト電極５０を有する、腐食センサ。【選択図】図２
