An electromagnetic valve (1) as a fluid device is provided with a valve seat (110) and a valve body (25) midway of a flow path (11) where a liquid flows, and closes the valve with the valve body (25) pressed onto the valve seat (110) and opens the valve by causing a gap between the valve seat (110) and the valve body (25). The electromagnetic valve includes, as electrodes for measuring a degree of electrical conductivity between a liquid on an upstream side and a liquid on a downstream side of the valve seat (110) and the valve body (25) in the flow path (11), a first electrode (141) electrically conductive to the liquid on the upstream side and a second electrode (142) electrically conductive to the liquid on the downstream side. By using the first and second electrodes (141 and 142), detection of liquid leakage can be easily performed.
