The present invention relates to a camera module in which a thin camera module can be realized at a low cost and an electronic device. The camera module includes a lens unit that stores a lens that condenses light on a light receiving surface of an image sensor; a rigid substrate on which the image sensor is disposed; and a flexible substrate electrically connected with the rigid substrate, wherein in the case where the light receiving surface of the image sensor locates at the top, the lens unit, the flexible substrate, and the rigid substrate are disposed in this order from the top.
