PROBLEM TO BE SOLVED: To provide an easily-manufacturable liquid leakage sensor capable of detecting leakage liquid at a time on a plurality of optional positions. SOLUTION: A plurality of detection parts for detecting leakage liquid are disposed in a transparent or translucent flexible fixed member, to thereby enable detection of the leakage liquid at one time on the plurality of optional positions. Each leakage liquid detection part is constituted of an optical system detection part and a capacitance system detection part. The optical system detection part comprises a means for irradiating light, a prism and a light receiving means, and determines existence of the leakage liquid by a light reception amount by the light receiving means. The capacitance system detection part comprises a pair of electrodes arranged contactably with the leakage liquid, and an oscillator, and determines existence of the leakage liquid and its kind by output from the oscillator.
