    • PROBLEM TO BE SOLVED: To provide a spout for foaming beverage which can generate very small foam of the foaming beverage in a receiver by reliably generating a small auxiliary flow before generating the main flow at a desired speed. SOLUTION: This spout for the foaming beverage which is fitted to a metal vessel closed by a top plate having an unsealing part comprises a projecting bar 61 brought into contact with an outer surface of the top plate, a body 2 which covers and is fitted to the top plate, a main nozzle fitted to one side of the body in a diagonally protruded manner from the body at a matching position with the unsealing part, and an auxiliary nozzle 4 which is adjacent to the main nozzle, expanded parallel to the main nozzle, and fitted to the body. The main nozzle and the auxiliary nozzle are disposed on the center side of the body and on the outer circumferential side of the body, respectively, an introduction chamber 5 in which the area of an opening part is larger than the area of the unsealing part of the top plate is formed on an entrance of the main nozzle and the auxiliary nozzle, and the auxiliary nozzle has a first nozzle hole 42 having the large sectional area on the upstream side along the fluid flowing direction and a second nozzle hole 43 having the small sectional area on the downstream side.
