1. An endoscope having:
- an image forming objective system contained in the tip part of an insertion part formed to be elongate so as to be insertable into a body cavity or the like;
a solid state imaging device having a photoelectric converting function and arranged so as to have its imaging surface located in the focal plane of said objective system; and
a substrate having said solid state imaging device fixed thereon and having conductive parts electrically connected with the electrodes of said solid state imaging device,characterized in that said conductive parts are formed on at least one side surface of said substrate and said solid state imaging device is fitted onto said substrate while, for electrodes located on at least one end surface side in said solid state imaging device placed on said substrate so as to be adjacent to said conductive parts, one side surface of said conductive parts retreats to be below the same level as of said electrode position.

Abstract
A solid state imaging device and a substrate to which this solid state imaging device is fitted is contained in the tip part of an endoscope. Conductive parts are formed on at least one side surface of the substrate. The positions of the conductive parts, when that the conductive parts are overlapped with the solid state imaging device, are retreated to be within the electrode positions of the solid state imaging device so that the imaging device may be contained in a small space.
