Abstract: In optical equipment, an image pickup element is not electrically connected directly to a hard electric board, but is electrically connected thereto via a flexible printed circuit. Since the image pickup element and the hard electric board are electrically connected via the flexible printed circuit, thermal effect of soldering or effect of deformation of the hard board can be alleviated. Since the flexible printed circuit has flexibility, the image pickup element can easily be positioned at an accurate position at the time of assembly. Also, it can hardly be affected by aged deformation.
