Abstract
An endoscope apparatus comprises: an insertion section including a distal end; a power changing movable lens that makes observational magnification variable, the power changing movable lens being movably built in an objective optical system provided at the distal end; a linear transmission member that drives the power changing movable lens, the linear transmission member being disposed from a drive section provided at a position other than the insertion section to the distal end; a focus adjusting movable lens that achieves automatic focusing function, the focus adjusting movable lens being movably built in the objective optical system separately from the power changing movable lens; and an actuator that drives the focus adjusting movable lens, the actuator being arranged in the distal end.
