Abstract
A printed circuit board structure for a scope unit of an electronic endoscope system, which is provided with a first printed circuit board formed with a first circuit section, and a second printed circuit board formed with a second circuit section. The first printed circuit board is piled on the second printed circuit board. The second printed circuit board having an area covered with the first printed circuit board and at least one area which is not covered with the first circuit board. The at least one area is used for electrically connecting the second circuit section with an electrical unit other than the second circuit section.
