The present invention is a water spouting apparatus (1) that discharges water with reciprocal motion, and has a water spouting apparatus body (10) and a oscillation generating element (22). The oscillation generating element includes a water supply conduit (24), a collision part (30) that generates a vortex on the downstream side, a vortex street conduit (26) provided downstream of the water supply conduit, and a discharge conduit that discharges water guided by the vortex street conduit. The vortex street conduit is configured by connecting the upstream member (18) on which the upstream side is formed and the downstream member (20) on which the downstream side is formed. At the connection between the upstream and downstream members, the height of the vortex street at the upstream end of the downstream member (H2) is higher than the height (H1) of the vortex street at the downstream end of the upstream member.
