The purpose of the present invention is to provide a visual inspection device and a printed solder inspection device that are capable of displaying 3D measurement results using a phase shift method and also capable of 2D measurement. The printed solder inspection device (1) comprises: a pair of first illumination devices (2) capable of radiating phase-shifted light from two opposite directions diagonally above the object to be inspected (100); a second illumination device (3) capable of radiating RGB light onto the object to be inspected, from above; and an imaging device (4) capable of capturing monochrome images of the object to be inspected. Said device irradiates the same imaging surface of the object to be inspected with the bi-directional phase-shifted light and captures an image thereof, and, either before or after said image capture, sequentially irradiates with the RGB light the same imaging surface of the object to be inspected and captures an image thereof; and uses an image that combines each image to inspect the external appearance of the object to be inspected. |
