An endoscopic apparatus comprises: a movable lens that is movably built in an objective optical system arranged at a tip of an insert part of an endoscope a piezoelectric-element drive mechanism that causes the movable lens to move forward and backward in an optical axis direction due to driving of a piezoelectric element a control circuit that provides a drive pulse to the piezoelectric element and a storage section that stores respective ones of drive-pulse count data for moving the movable lens forward and backward equally in amount, wherein the control circuit performs control of providing a drive-pulse count, different in between forward and backward movement, to the piezoelectric element of the piezoelectric-element drive mechanism so as to move the movable lens forward and backward equally in amount depending upon drive-pulse count data read out of the storage section.
