PROBLEM TO BE SOLVED: To provide a water discharge device in which film-like water streams are discharged in a wide range, and which has high relaxation effect, and to provide a bathtub device.SOLUTION: A water discharge device (1) includes: a supply channel; a slit-like water discharge port (2) discharging water supplied from the supply channel; and a film-like water formation mechanism provided between the supply channel and the water discharge port, and discharging film-like water streams from the water discharge port. The water discharge port is formed along a shape of an upper edge part of a bathtub (101), and the film-like water streams of a substantially U shape in plane view can be discharged from the water discharge port by the film-like water formation mechanism.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2020,JPO&INPIT【課題】膜状の水流が広範囲で吐水され、リラックス効果の高い吐水装置及び浴槽装置を提供する。【解決手段】本発明の吐水装置(1)は、給水路と、前記給水路から供給された水を吐水するスリット状の吐水口(2)と、前記給水路と前記吐水口との間に設けられ、膜状の水流を前記吐水口から吐水させる膜状水形成機構と、を備え、前記吐水口が浴槽(101)の上縁部の形状に沿ってて形成されて、前記膜状水形成機構により前記吐水口から平面視略U字型の膜状の水流が吐水可能に構成されていることを特徴とする。【選択図】図2
