An automatic faucet control device including an electromagnetic valve for opening and closing a flow channel of a faucet, a ray emitting device () for emitting infrared rays to a target to be detected, a ray receiving device () for receiving the infrared rays reflected by the target, a sensing decision device for the deciding presence or absence of the target by an output from the ray receiving device (), and an electromagnetic valve controller for controlling the electromagnetic valve based on a signal from the sensing decision device. The ray emitting device () has a first polarizing plate () allowing a polarized light component to be transmitted, and the ray receiving device () has a second polarizing plate () for allowing a polarized light component different from the rays transmitted through the first polarizing plate () to be transmitted therethrough.
