Abstract
Provided is an automatic faucet using a radio wave sensor, which is capable of preventing erroneous stop of water spouting, with a simple configuration. The automatic faucet () has a radio wave propagation space, a radio wave emitting port (), and directivity setting device. The directivity setting device is configured to direct a radio wave being emitted from the radio wave emitting port (), in such a manner that, during a water stopping state, the emitted radio wave lies along a spouting direction (A) along which washing water is to be spouted from a spout port (), and, during a water spouting state, a part of the radio wave emitted disposed offset in a direction C, with respect to the spout port () interferes with a region of a peripheral surface of a stream (W) facing in the direction C.
