A shower apparatus for discharging aerated bubbly water, comprising: a water supply unit adapted to supply water; a throttle unit installed downstream of the water supply unit, and adapted to make a cross sectional area of a flow channel smaller than the water supply unit and thereby eject passing water downstream; an aeration unit installed downstream of the throttle unit and provided with an opening adapted to produce the bubbly water by aerating the water ejected through the throttle unit, and side walls (23eb, 23fb) placed obliquely so as to expand the flow channel outward from a downstream portion; and a nozzle unit installed downstream of the aeration unit, comprising a nozzle face having a plurality of nozzle holes adapted to discharge the bubbly water by being formed along an ejection direction of the water ejected through the throttle unit, wherein the throttle unit comprises a throttle channel formed into a flat shape whose longer sides run along the nozzle face, wherein a partition wall is installed in a boundary portion between the throttle unit and the aeration unit, and the throttle channel is formed in the partition wall; and the water ejected from the throttle channel becomes a sheet-like stream of water which plunges into an air-liquid interface by involving air taken in through the opening and thereby producing bubbly water, which is then discharged through the nozzle holes, where the air-liquid interface is an interface between air and water, the water having been temporarily pooled in at least part of the aeration unit and the nozzle unit, characterised in that the sheet-like stream of water is ejected downstream to the aeration unit and the nozzle unit from the throttle channel such that a virtual water ejection straight line will extend to the most distant nozzle hole while avoiding interference with side walls of the aeration unit and side walls of the nozzle unit. a water supply unit adapted to supply water; a throttle unit installed downstream of the water supply unit, and adapted to make a cross sectional area of a flow channel smaller than the water supply unit and thereby eject passing water downstream; an aeration unit installed downstream of the throttle unit and provided with an opening adapted to produce the bubbly water by aerating the water ejected through the throttle unit, and side walls (23eb, 23fb) placed obliquely so as to expand the flow channel outward from a downstream portion; and a nozzle unit installed downstream of the aeration unit, comprising a nozzle face having a plurality of nozzle holes adapted to discharge the bubbly water by being formed along an ejection direction of the water ejected through the throttle unit, wherein the throttle unit comprises a throttle channel formed into a flat shape whose longer sides run along the nozzle face, wherein a partition wall is installed in a boundary portion between the throttle unit and the aeration unit, and the throttle channel is formed in the partition wall; and the water ejected from the throttle channel becomes a sheet-like stream of water which plunges into an air-liquid interface by involving air taken in through the opening and thereby producing bubbly water, which is then discharged through the nozzle holes, where the air-liquid interface is an interface between air and water, the water having been temporarily pooled in at least part of the aeration unit and the nozzle unit, characterised in that the sheet-like stream of water is ejected downstream to the aeration unit and the nozzle unit from the throttle channel such that a virtual water ejection straight line will extend to the most distant nozzle hole while avoiding interference with side walls of the aeration unit and side walls of the nozzle unit.
