PROBLEM TO BE SOLVED: To provide an apparatus that can accurately inspect a mount state of electronic components. SOLUTION: A mount state-inspecting apparatus picks up a color image of a mounted substrate 5 by a color camera 11, thereby inspecting a mount state. In the apparatus, a white light introduced from a white light source part 19 is projected from end parts 17a of fiber cables 17 arranged uniformly in a plurality of circles to a reflecting part 16 having an opening part 16a at an upper part and a hemispherical diffusion reflection face, so that the mounted substrate 5 is illuminated with the diffused and reflected white light. Generation of shades and gloss of electronic components because of the illumination is thus eliminated. A colored light from a colored light source part 20 is projected by a half mirror 21 to the mounted substrate 5 from the same axial direction as the color camera 11, so that a polarity mark having a smooth reflection face of different surface roughness from other parts can be detected. |
