PROBLEM TO BE SOLVED: To provide a faucet device capable of accurately determining abnormality of a power generation part which generates electric power to drive a solenoid valve for switching water discharge and water cutoff.SOLUTION: A faucet device 1 includes: a solenoid valve 16 for opening and closing a water channel 14; a power generation unit 8 for generating electric power to drive the solenoid valve 16 by a water wheel rotated by flow of water; a water purification unit 10 for purifying water flowing through the water channel 14; and a controller 6 for controlling the operations of the solenoid valve 16 and the power generation unit 8. The controller includes: a flow rate information calculation section 6d for calculating first flow rate information related to passing water which has passed through the water purification unit 10 on the basis of a power value generated in the power generation unit 8, and calculating second flow rate information related to the passing water which has passed through the water purification unit 10 on the basis of an output value generated in the power generation unit 8 in the case that the first flow rate information is a prescribed rate or lower; and an abnormality determination section 6e for determining that the power generation unit is abnormal in the case that the second flow rate information calculated by the flow rate information calculation section is a prescribed rate or lower.
