To provide a device for sterilizing and cleaning a container which can certainly sterilize the container while suppressing the amount of a cleaning liquid used, and to provide a nozzle for injecting the cleaning liquid at a low cost.

The cleaning liquid injected into the container 100 from the nozzle 50 is made to move onto the inner surface 100c of the container 100 by centrifugal force by forming a coma member 52 with a spiral groove 54 at the tip end part of the nozzle 50 in a freely rotational way, while the cleaning liquid is discharged to the outside of the container 100 through a clearance between the inner wall surface 100d of the mouth part 100a of the container 100 and the outer peripheral side of the nozzle 50. Hence, the interference with the cleaning liquid injected from the nozzle 50 is prevented in the inner side of the mouth part 100a and the sterilization with the cleaning liquid is certainly performed over the whole part of the container 100 even at a low flow rate.
