Abstract:
1. A camera module comprising: a solid-state imaging device including a semiconductor substrate, on a first surface of which light-receiving elements are formed; an optical unit having a built-in photographic optical system for forming a subject image on said light-receiving elements; an electronic component for driving said solid-state imaging device, a first surface of said electronic component being attached to a second surface of said semiconductor substrate, which is opposite to said first surface of said semiconductor substrate, and said electronic component being electrically connected to said solid-state imaging device; and a circuit board provided with a circuit for driving said solid-state imaging device, said circuit board being attached to a second surface of said electronic component, which is opposite to said first surface of said electronic component, and said circuit board being electrically connected to said solid-state imaging device, wherein said first surface of said semiconductor substrate is used as an assembly reference plane when said solid-state imaging device and said optical unit are combined.
