ABSTRACT:
An endoscope having a distal end portion including an objective lens system and a solid-state image pickup device. An optical member having a diameter larger than that of the objective lens system is arranged between the objective lens system and the solid-state image pickup device. Only the objective lens system is supported by a supporting frame. Thus, the diameter of the distal end portion of the endoscope can be reduced.
