<P>PROBLEM TO BE SOLVED: To provide an oil leakage detector which detects leakage of oil by simple structure regarding the oil leakage detector which detects oil leakage from equipment. <P>SOLUTION: An oil leakage detector is constituted by including: a light source part 2 for detection, which projects light of which the attenuation to water has wavelength larger than that of the attenuation to oil to a detection object area of oil leakage; and a determination part 4 which determines the presence/absence of the oil leakage on the basis of reflected light projected from the light source part 2 for detection and reflected on the detection object area. <P>COPYRIGHT: (C)2013,JPO&INPIT |
