Beverage supply nozzle

The present invention provides a beverage supply nozzle capable of suppressing a decrease in air capacity and ensuring a predetermined discharge time. The beverage supply nozzle (10) is formed of a hollow tubular body (20) and a polygon prism-shaped resistance body (30) disposed in the inside of the tubular body (20) to expel carbonated water, wherein the resistance body (30) is formed in a radial direction at least a double structure composed of an inner resistance body (32) and an outer resistance body (31), the inner resistance body is formed as a solid polygonal prism, the hollow tubular outer wall of the outer resistance body is formed into a polygon, a gap formed between the outer flat surface portion of the outer resistance body (31) and the inner wall surface of the tubular body (20) and a gap formed between the flat surface portion of the inner resistance body (32) and the inner wall surface of the outer resistance body (31) are taken as pressure reducing portions to reduce the air capacity, and the
