A one electrode Da including a contact T is provided at an aperture edge of the supply aperture and/or a peripheral part of an aperture edge of the body. The body includes another electrode Db, and stores a valve member made of a conductor and opening and closing the supply aperture, and a coil spring made of a conductor and urges the valve member. A guide member made of a conductor is attached onto the valve member. The guide member is formed to secure a flow path of the fluid from the supply aperture to the discharge aperture while being slidable in the fluid space E, has a reception surface facing one end face of the fluid space E while receiving the fluid from the supply aperture.
