The invention relates to a nozzle for a combustion chamber, the combustion chamber and a gas turbine. A nozzle for a combustion chamber for combusting hydrogen-containing fuel according to one embodiment of the present invention comprises: a first tube for allowing fuel to move and having a fuel injection port formed at the tip thereof for injecting the fuel; the second pipe surrounds the first pipe, and the front end of the second pipe is provided with a premixing injection opening for discharging air and fuel after the air and the fuel are mixed; and a third tube surrounding the second tube and allowing fuel to move; the second tube has formed therein a plurality of micro-injection holes that receive the fuel from the third tube and form a micro-flame, and the plurality of micro-injection holes may be disposed at intervals in the peripheral direction of the second tube. According to the nozzle for the combustion chamber, the combustion chamber and the gas turbine, flames can be stably kept when hydrogen-con
