The present invention provides a structure of a water discharge portion and a shower device which are low in cost and capable of ejecting pulsed hot water without weakening the water potential from the primary side as much as possible without interrupting it. The configuration of a water discharge portion (1) has an upstream side member (4) having a plurality of water inflow ports (2) on the center side, a sloped auxiliary water passage (10) on the peripheral side, and an annular holding portion (3) for holding balls at a position closer to the outer side than the water inflow ports (2) on theinner surface; a downstream side member (7) having a water outlet (5) at the center and an annular holding portion (6) for holding balls on the inner surface; and a plurality of balls (8) which are balls for generating a Coanda effect, and are held by the annular holding portion (3) of the upstream side member (4) and the annular holding portion (6) of the downstream side member (7).
