Abstract
In a suction nozzle, a tip portion of an air pipe includes an opening portion having an area larger than that of a flow path of the air pipe, and a slit which is formed on the tip portion of the air pipe is provided in a portion of a circumferential contact surface contacting the component. In the suction nozzle, since air supplied from the air pipe flows out through the slit, the suction state of the component is canceled from the position of the slit as a base point.
