The present invention provides a shower apparatus that allows the user to have a shower stream with a voluminous feel, even when a small volume of water is discharged, and also with a stimulus sensation arising from water being discharged in a pulsating manner. A shower apparatus F1 periodically changes the volume of air taken into an aeration unit 43 by oscillating a main water stream ejected toward the aeration unit 43 from a throttle unit 42 in a direction crossing the direction of the ejection, so that the bubbly water discharged from a water discharge unit 44 creates a pulsating shower stream.
