PROBLEM TO BE SOLVED: To provide a device for inspecting solder for appearance that can improve a function of identifying the applied state of solder applied to an electrode further enhancing the contrast between the electrode and solder. SOLUTION: This device for inspecting solder for appearance is provided with a light source 3 which projects light containing ultraviolet rays upon an object to be inspected including the electrode 9 containing copper of gold in its external surface as the main component and the solder 10 applied to the electrode 9, a camera 4 which picks up the images of the electrode 9 and solder 10 in an ultraviolet region with the light reflected on the object by receiving it, and a discriminating section 5 which discriminates the applied state of the solder 10 from the images picked up by means of the camera 4.
