Abstract

A holding apparatus including a suction nozzle which applies a negative pressure to a back surface of an object and thereby holds the object, a front-surface lighting device which emits a first visible light toward a front surface of the object held by the suction nozzle and thereby lights the front surface, and a back-surface lighting device which lights the back surface of the object held by the suction nozzle and which includes a light emitting plate which is provided around a base portion of the suction nozzle and emits a second light from a light emitting surface thereof facing a side of a free end of the suction nozzle that holds the object; and a dark infrared-ray transmitting filter which is dark, covers the light emitting surface of the light emitting plate, and transmits infrared rays of the second light.
