An objective lens for an endoscope is provided and has a lens group A and a lens group B that are movable in a direction of an optical axis. In the objective lens, first focal adjustment for observing a point between a most-distant point and an intermediate point is performed by moving the lens group A from a lens arrangement for observing the most-distant point; and second focal adjustment for observing a point between the intermediate point to a nearest point is performed by moving the lens group B from a lens arrangement for observing the intermediate point.
