A combustor includes a nozzle, a burner cylinder (43) surrounding the outer circumference of the nozzle, and an outside flow path cylinder (60) surrounding the outer circumference of a downstream end portion of the burner cylinder (43). A purge air flow path (66) through which air (A1) flows is formed between the inner circumferential side of the outside flow path cylinder (60) and the outer circumferential side of the burner cylinder (43).
