A nozzle (7) for cleaning a lens surface (1a) of a camera (1) is provided, the nozzle (7) includes a cleaning liquid path (11a), (11b) that guides a cleaning liquid to a discharge port (10a), (10b) and an air passage (12) that guides a compressed air to a discharge port (10a), (10b). Furthermore, a distal end portion of the cleaning liquid path and a distal end portion of the air passage are disposed so as to be proximate to each other, or are disposed so as to be merged with each other. Then, at the time of cleaning the lens surface (1a), the compressed air is made intermittently jet from the discharge port, and the cleaning liquid is suctioned with the negative pressure occurring due to the jetting of the compressed air to make the cleaning liquid intermittently jet from the discharge port, thereby cleaning the lens surface (1a).
