<P>PROBLEM TO BE SOLVED: To provide a liquid detector capable of identifying a liquid attached to an optical fiber even when a plurality of detection target liquids exist. <P>SOLUTION: The liquid detector includes: the plurality of optical fibers, each having a bent part; light emitting elements, each individually provided to each of the optical fibers and making light corresponding to an electric signal externally inputted incident on one end of the optical fiber; and light receiving elements, each individually provided to each of the optical fibers and externally outputting the electric signal corresponding to light emitted from the other end of the optical fiber. A bent radius of the bent part of each optical fiber is set corresponding to a refraction factor of the detection target liquid of which the optical fiber is in charge. <P>COPYRIGHT: (C)2012,JPO&INPIT |
