PROBLEM TO BE SOLVED: To provide a jet bath apparatus discharging diversified jet flows in a small-size and simple structure. SOLUTION: A jet nozzle has a stream introduction part and a chamber extending in the axial direction of a tubular body and formed inside the tubular body, wherein the stream introduction part has an upstream-side end part for introducing pressured bathtub water sent from a pressure device, and a downstream-side end communicated with the chamber, and the chamber has a channel cross section sudden expansion part provided in the axial upstream-side end and having the channel cross section suddenly expanded with respect to the downstream-side end of the stream introduction part, and a spout opened in the axial downstream-side end part. The channel of the channel introduction part is gradually narrowed from the upstream-side end part toward the downstream-side end part, a channel center line passing through the center of the channel cross section of the stream introduction part has a curvature and the downstream-side position of the channel center line is accorded with the axial center of the chamber.
