摘要： The present invention is a spout apparatus including: a spout forming member configured to form a spout; a flow-guiding member provided inside the spout forming member, configured to guide water on an upstream side of the spout; an exposed flow-guiding member provided inside the spout forming member and on a spout side of the flow-guiding member, and exposed on a spout side of the exposed flow-guiding member; and a water channel configured to supply the water to an upstream side of the flow-guiding member. The exposed flow-guiding member and/or the spout forming member are configured to spout water from an outer periphery as an annular stream, among the water spouted from the spout. According to the above spout apparatus, the flow-guiding member can be effectively protected, and high guiding characteristics can be achieved in particular at an outer periphery of the spout.
