Claim:
1. An imaging module, comprising: a substrate on which an imaging sensor is mounted; a plurality of lenses for imaging light from an object on the imaging sensor; and a focus adjustment mechanism which adjusts focus of the plurality of lenses and is fixed to the substrate, wherein the focus adjustment mechanism includes a movable portion which is displaced in an optical axis direction of the plurality of lenses and a non-movable portion which is not displaced in the optical axis direction, a first lens group formed of two or more lenses selected from the plurality of lenses is fixed to an inner peripheral wall of the movable portion, and a second lens group formed of one or more lenses not included in the first lens group and selected from the plurality of lenses is fixed to an inner peripheral wall of the non-movable portion, the second lens group is arranged between the first lens group and the imaging sensor, and an angle formed by light incident from the first lens group on the second lens group and the optical axis is greater than an angle formed by the light incident from the first lens group on the second lens group and output from the second lens group to the imaging sensor and the optical axis.
