Abstract
A suction nozzle includes a suction pad portion at a tip of an air pipe formed to be larger than the air pipe, in which a resistance cavity which causes resistance and decreases air flow speed when a positive pressure is applied is formed between a flow path and a cavity portion. In the suction nozzle, since the resistance cavity is formed, a positive pressure is applied by the air whose flow speed is suppressed and the suction release of the component is performed. The resistance cavity may be a cavity having a slit shape.
