ABSTRACT:
Disclosed is an appearance inspection apparatus for inspecting whether an appearance state of a main actuator element is adequate or defective by applying an appearance-inspecting voltage to the main actuator element including an upper electrode formed on an upper surface of a shape-retaining layer and a lower electrode formed on a lower surface of the shape-retaining layer. The appearance inspection apparatus comprises an optical detecting unit for electrically detecting the appearance state of the main actuator element on the basis of light emission caused by the main actuator element, and a judging unit for judging whether the appearance state of the main actuator element is adequate or defective on the basis of a level of a detection signal supplied from the optical detecting unit. Accordingly, it is possible to realize high inspection accuracy, reduce inspection time, and simplify the inspection apparatus. Further, the present invention is also applicable to integrated electronic parts.
