PROBLEM TO BE SOLVED: To provide an appearance inspecting device of a simple configuration which can efficiently inspect the appearance of a micro chip-like electronic part. SOLUTION: First to third cameras 11, 21, and 31 which image the upper surface as well as left and right side surfaces of an chip-like electronic part P of almost rectangular parallelopiped along a transportation path of a belt conveyor mechanism 3 on which the electronic part P is placed and carried in one direction for appearance inspection, are provided. A transportation drum 4 is provided wherein the upper surface of the electronic part of P is held by adhesion on the surface on the downstream of the belt conveyor mechanism for transfer from the belt conveyor mechanism so that the lower surface of the electronic is imaged with a fourth camera 41. Thus, the lower surface of the electronic part is exposed to the camera 41 during transportation.
