PROBLEM TO BE SOLVED: To provide a focusing device capable of quickly moving a lens to a focus fine adjustment area and realizing fine movement that the lens is focused in the focus fine adjustment area. SOLUTION: A lens moving mechanism to move the lens 5 in an optical axis direction includes a 1st guide part to guide the lens 5 so as to move in the optical axis direction by a 1st prescribed distance to the focus fine adjustment area and a 2nd guide part to guide the lens 5 so as to finely move in the optical axis direction by a 2nd prescribed distance in the focus fine adjustment area. For example, the 1st guide part is constituted of the inclined parts 8a12 and 8a22 of the guide grooves 8a1 and 8a2 of an outer cam 8, and the 2nd guide part is constituted of the 1st cam body 4a1 and the 2nd cam body 4a2 of a lens holder 4.
