摘要： PROBLEM TO BE SOLVED: To provide a liquid leakage detection sensor having satisfactory detection sensitivity as a sensor with detection time shortened of a liquid leakage such as oil, with the replacement of a spent liquid sensitive material facilitated.
SOLUTION: A hemispherical end part of a switch body 1 is in contact with a liquid leakage detection body 4 with a backing plate 3 interposed between them. Further, the switch body 1, which is urged in the direction of an arrow in the figure, is in a state of being pressed down by the backing plate 3. If a liquid leakage occurs under such a state, the liquid leakage comes within a case 2 through an opening part 5b in a front middle part and two opening parts (holes) 5c in a side surface, these openings provided on an enclosure 5, and a liquid sensitive material 7 put inside a metallic ring 6 of the detection body 4 dissolves in the liquid leakage. Since the switch body 1 is urged in the direction of the arrow, the switch body 1 moves in the direction of the arrow so as to fill a space developed owing to the dissolution of the sensitive material 7, causing the operating state of a switch to change, through which the liquid leakage is detected.
