Suction nozzle, and electric-component-position detecting apparatus

摘要

A suction nozzle (64) for applying a suction to an object (28) and thereby holding the object, the suction nozzle including a nozzle portion (122) having an end surface (70), and a suction passage (128) formed in the nozzle portion and opening in the end surface thereof, the end surface providing a suction surface (70) that applies the suction to the object and thereby holds the object. At least a free end portion of the nozzle portion (122) has a shape whose diameter gradually increases in a direction from the end surface (70) thereof toward a base end thereof opposite to the end surface.
