It has a gas reservoir that is formed and a gas supply pipe that reaches the nozzle body from the outside of the iron shell, allowing the molten metal in the tundish to flow toward the mold, and supplying inert gas to the gas reservoir via the gas supply pipe. In an insert nozzle for continuous casting that stores inert gas and supplies inert gas from this gas reservoir to the inside of the nozzle body through the nozzle body, a portion of the outer peripheral surface of the nozzle body above the gas reservoir is formed of a dense refractory. An insert nozzle for continuous casting characterized by:
