特徴とする漏液センサ。 A porous material containing a conductive material is used as a sensing part that causes a change in electrical resistance when liquid leakage is absorbed by dispersing a fine conductive material in the pores of porous tetrafluoroethylene around the core member. In a liquid leakage sensor in which tetrafluoroethylene is arranged to detect the presence or absence of liquid leakage, the porous tetrafluoroethylene containing a conductive substance is formed into a thin tape shape and placed around the core member. A liquid leakage sensor characterized by having a cylindrical sensing portion formed by winding.
