In an endoscope used for medical treatment, a sleek design of the insertion tube section of the endoscope and a reduction in length of a rigid portion at the distal end of the insertion tube section are demanded in order to improve its operation property. It is thus indispensable that the objective lens used in the endoscope is constructed so that aberration is completely corrected in practical use, a lens contour is small, and the entire length is reduced.
