PROBLEM TO BE SOLVED: To provide a power generator for a faucet, capable of suppressing variation in torque imposed on a moving blade even if the length of a direction substantially orthogonal to the diameter direction of a moving blade vane portion is shortened. SOLUTION: The power generator for a faucet includes: the moving blade 15 having the moving blade vane portion 19 having a rotation center substantially parallel to a water supply passage and rotatably provided on the water supply passage, and a moving blade diametrical outside portion provided on the diametrical outside direction of the moving blade vane portion 19 and equipped with an integrally rotatable magnet; and a stator 9 having a coil for generating an electromotive force, a yoke provided so as to surround the coil and a plurality of inductors 31a, 32a protruding from the yoke and provided so as to be spaced from each other. The inductors have a portion opposing a surface substantially orthogonal to the end surface of upstream or downstream side of the magnet so as to be spaced from each other, and a downstream end surface of the moving blade vane portion 19 and a downstream end surface of the moving blade diametrical outside portion are provided so as to be spaced from each other so that the downstream end surface of the moving blade vane portion 19 may be positioned closer to the upstream side than the downstream end surface of the moving blade diametrical outside portion to the extent of suppressing variation in rotation of the moving blade 15 or noise.
