PROBLEM TO BE SOLVED: To appropriately focus a subject image without performing processing using a high-performance CPU or special software. SOLUTION: In the imaging apparatus 100, a first cam-shaped part 61A and a second cam-shaped part 61B having: an inclined face part A3, B3 for displacing a lens part 4 in an optical axis direction with respect to an imaging device 3; a base end face part A1, B1 continuously provided at one end of the inclined face part; and a top end face part A2, B2 continuously provided at the other end of the inclined face part on an opposite side to the base end face part, are formed on the cam surface 611 of a cam member 6 for displacing the lens part 4 in the optical axis direction with respect to the imaging device 3. The cam-shaped parts are disposed on the basis of the shortest focusing distance of the lens part so that the distances of the top end face parts to the imaging device are different.
