The vibration device includes a piezoelectric element having a connection terminal exposed from a main surface of the piezoelectric element, a first resin layer having conductivity and covering the connection terminal of the piezoelectric element to be electrically connected to the connection terminal, a wiring member overlapping the main surface of the piezoelectric element to cover the first resin layer, including a wire electrically connected to the first resin layer, and extending beyond one end of the piezoelectric element when viewed in a thickness direction of the piezoelectric element, and a second resin layer integrally covering the main surface of the piezoelectric element and the wiring member. The second resin layer includes a first layer in direct contact with the piezoelectric element and the wiring member, and a second layer covering the piezoelectric element and the wiring member via the first layer.

A pit gate includes a gate body which is inserted between a pool portion storing water and a canal portion connected to the pool portion and is configured to change a flow state of the water, and a seal portion () which is accommodated in a groove-shaped accommodation recess formed in the gate body and seals between the pool portion and the gate body. The seal portion () includes a low-rigidity portion () which is relatively easily deformed by a load according to a water pressure from the pool portion side, and a high-rigidity portion () which is provided on the pool portion side of the low-rigidity portion and is not easily deformed relatively by the load.
