Abstract: The present application relates to a base (10), a camera module (100) and an electronic device (1000). The base (10) is used for bearing a lens (20), and comprises: a substrate (1) connected to the lens (20), the substrate (1) being provided with a mounting hole (13); a photosensitive chip (2) arranged in the mounting hole (13) and opposite the lens (20); and a support structure (6) arranged in the mounting hole (13), connected to an inner wall (131) of the mounting hole (13) and connected to a surface, away from the lens (20), of the photosensitive chip (2) so as to support the photosensitive chip (2).
