Abstract
There is provided an optical module having a circuit board that includes an imaging element, a lens barrel that is fixed onto the circuit board to movably accommodate a lens holder having a lens that forms an image on an imaging surface of an imaging element in a light axis direction, a cylindrical cam having a cam surface engaged with a protrusion disposed in the outside of the lens barrel and extending from a side face of the lens holder to move the lens holder, and a drive section in which an actuator drives the cylindrical cam via a gear train and also having a cover that integrally covers the lens barrel and the actuator and determines the positional relationship between the lens barrel and the drive section.
