1. A camera module which is attached to an inner side of a windshield of a vehicle and works to capture an image of an outside view from the vehicle, comprising:
an imager configured to capture an image of an outside view;
a lens set comprising an outside view lens and a small-diameter lens located closer to the imager than the outside view lens is and through which light from the outside view passes to form an image in the imager;
a lens barrel within which the lens set is disposed; and
an inner lens barrel disposed within the lens barrel and includes the small-diameter lens disposed therein,
wherein the lens barrel includes a lens barrel axial force applying portion which retains the outside view lens using an axial force oriented along an optical axis of the lens set, and
wherein the inner lens barrel is disposed between the small-diameter lens and the outside view lens and comprises an axial force-transmitting portion which transmits the axial force from one of the small-diameter lens and the outside view lens to the other,
wherein the small-diameter lens is smaller in diameter than the outside view lens,
wherein the outside view lens comprises a rear supporting surface extending substantially perpendicular to the optical axis, and
wherein the axial force-transmitting portion is arranged between the outside view lens and the small-diameter lens,
wherein the axial force-transmitting portion comprises an end portion that is in contact with the rear supporting surface of the outside view lens, and
wherein the end portion protrudes radially inward toward the optical axis and is positioned radially closer to the optical axis than an outer peripheral supporting surface of the small-diameter lens.
