Embodiment Construction
[0082] Below, based on Figure 1 to Figure 14 , Figure 16 ~ Figure 20 Embodiments of the present invention will be described.
[0083] figure 1 It is a perspective view of the camera module of this embodiment. The camera module 100 includes: an optical unit 1 as an imaging optical system; a lens driving device (lens driving unit) 2 that drives the optical unit 1 ; and an imaging unit 3 that photoelectrically converts light passing through the optical unit 1 . The optical unit 1 is held inside the lens driving device 2 . The imaging unit 3 is configured to include a sensor unit 4 and a substrate 5 on which the sensor unit 4 is mounted. The camera module 100 is configured by laminating the sensor unit 4 and the lens driving device 2 sequentially in the optical axis direction on the substrate 5 . In the following description, for convenience, the side of the optical unit 1 is referred to as the upper side, and the side of the imaging unit 3 is referred to as the lower side...

Abstract
The invention relates to a camera module, an electronic device including the same, and a method for positioning lenses of the camera module. In the camera module, the position of image pickup lenses at an end at infinity is defined by contact between a bottom surface of a lens barrel and a surface of a sensor cover. This makes it possible to realize a camera module having image pickup lenses positioned with a high degree of accuracy.
