Water discharge device

The invention provides a water discharge device which is provided with a vibration generating element which can be easily formed. The present invention is a water discharge device for discharging water while vibrating water back and forth, the water discharge device comprising a water discharge device body and a vibration generating element, the vibration generating element comprising: a water supply passage; a collision part that forms a vortex on the downstream side; a vortex train passage provided downstream of the water supply passage; and a discharge passage that discharges water guided by the vortex passage, the vortex passage being configured by connecting an upstream member formed on the upstream side thereof and a downstream member formed on the downstream side thereof, the height of the vortex passage at the upstream end of the downstream member being configured to be higher than the height of the vortex passage at the downstream end of the upstream member. In a connection portion between the upstre
