Abstract: In this shower apparatus, a part of an internal space thereof closer to the outer circumference thereof than an aeration unit is defined as a plurality of small spaces, and all of the small spaces have a uniform channel resistance, and all of the small spaces have a uniform ratio between a channel cross-sectional area at an inlet portion of each of the small spaces and a total opening area of nozzle holes that communicate the small space with an external space such that backflow water CF that returns from the respective small spaces consistently has a uniform flow rate at any point in time among the streams of the backflow water CF.

Abstract: Provided is a shower apparatus which can stably supply bubbly water through all nozzle holes and can cause water droplets of large, uniform size to land continuously on the user so as to allow the user to enjoy a shower with a voluminous feel as if the user were being showered by large drops of rain. The shower apparatus includes a water supply unit, a throttle unit adapted to eject passing water downstream, an aeration unit adapted to produce bubbly water by aerating the water ejected through the throttle unit, and a nozzle unit provided with a plurality of nozzle holes used to discharge the bubbly water, wherein the throttle unit has a flat-shaped throttle channel and water ejected through the throttle channel plunges into an air-liquid interface as a sheet-like stream, thereby producing bubbly water, which is then discharged through the nozzle hole.
