This corrosion detection sensor (101) detects corrosion of electrical equipment (900) by a caustic gas. This corrosion detection sensor (101) comprises a thin metal film (8) that becomes corroded by the caustic gas, a resistor (9) connected in series to the thin metal film (8), a resistance measurement instrument (20) measuring the combined resistance of the thin metal film (8) and the resistor (9), and a notification device (40) that provides notification of detection results that the combined resistance measured by the resistance measurement device (20) has exceeded a predetermined reference resistance. The reference resistance is defined according to the degree of risk that the electrical equipment (900) reaches a corrosion-damaged state due to the caustic gas. 腐蚀检测传感器(101)对由腐蚀性气体引起的电气设备(900)的腐蚀进行检测。腐蚀检测传感器(101)具有：金属薄膜(8)，其会因腐蚀性气体而被腐蚀；电阻器(9)，其与金属薄膜(8)串联连接；电阻测定器(20)，其对金属薄膜(8)和电阻器(9)的合成电阻进行测定；以及通知装置(40)，其通知由电阻测定装置(20)测定出的合成电阻超过规定的基准电阻这一检测结果。基准电阻与由于腐蚀性气体而使电气设备(900)达到腐蚀损伤的危险度相应地确定。
