Abstract
A suction nozzle for applying a suction to an object and thereby holding the object, the suction nozzle including a nozzle portion having an end surface, and a suction passage formed in the nozzle portion and opening in the end surface thereof, the end surface providing a suction surface that applies the suction to the object and thereby holds the object. At least a free end portion of the nozzle portion has a shape whose diameter gradually increases in a direction from the end surface thereof toward a base end thereof opposite to the end surface.

A suction nozzle for applying a suction to an object and thereby holding the object, the suction nozzle comprising:
- a nozzle portion having an end surface;
- a suction passage formed in the nozzle portion and opening in the end surface thereof;
- the end surface providing a suction surface that applies the suction to the object and thereby holds the object;
- at least a free end portion of the nozzle portion having a shape whose diameter gradually increases in a direction from the end surface thereof toward a base end thereof opposite to the end surface;
- a light radiating portion extending radially outwardly from a base end portion of the nozzle portion, and having a light radiating surface which radiates a light toward the object held by the nozzle portion;
- and
- an outer circumferential surface of at least the free end portion of the nozzle portion that has the shape whose diameter gradually increases in said direction comprising a mirror surface which reflects the light radiated by the light radiating surface,
- wherein an entirety of the light radiating surface is so inclined that a distance of the light radiating surface from the end surface of the nozzle portion in a direction parallel to an axis line thereof gradually increases in a radially inward direction.
