There is provided a camera module including a first lens substrate having a light-incident side. The first lens substrate includes a lens disposed at an inner side of a through-hole of the first lens substrate, and a wiring layer disposed at an opposite side of the light-incident side of the first lens substrate. The camera module may include an imaging element including a pixel array disposed at a light-incident side of a substrate, where the imaging element is electrically connected to the wiring layer of the first lens substrate, and where a width of the imaging element in a direction parallel to the light-incident surface of the imaging element is smaller than a width of the first lens substrate in the direction parallel to the light-incident surface of the first lens substrate.
