A faucet generator includes; a rotor vane which is disposed in a water supply channel; an annular magnet which is rotatable integrally with the rotor vane; and a stator having: a coil which is disposed to be opposed to an end face of the magnet that is substantially perpendicular to a radial direction; a plurality of inductors which are placed separately from one another along a circumferential direction between the end face of the magnet and the coil; and a yoke which is disposed to be continuously contacted with the inductor and surround the coil. The axial direction of the rotor vane is substantially parallel to the water supply channel. In the annular magnet, the end faces which are substantially perpendicular to a radial direction are alternately magnetized with N and S poles along the circumferential direction of the magnet. In the yoke, cutaway portions which are formed by cutting away portions that are opposed to the circumferential face portion of the coil, and that are in the vicinity of the tip ends of the inductors, in one end that is on the side where said inductors are disposed, whereby portions of the yoke which are in the vicinity of the tip ends of the inductors are formed so as to relatively recede from the magnetic inducible area of the magnet.
