Abstract:
A camera module and an electronic device. The camera module comprises a lens barrel and a first lens, and an object-side end surface of the lens barrel is provided with an opening; the first lens comprises a first optical portion opposite to the opening and a first ridge-fit portion surrounding the first optical portion; an image-side surface of the first ridge-fit portion comprises a first matching surface, a first ridge-fit surface, and a second matching surface which are successively connected; the side of the second matching surface away from the first ridge-fit surface is connected to an image-side surface of the first optical portion; the first matching surface and the second matching surface each form an included angle with the first ridge-fit surface; and the first matching surface, the first ridge-fit surface, and the second matching surface are all connected to the object-side end surface of the lens barrel. The first ridge-fit portion and the object-side end surface of the lens barrel are provided to be ridge-fitted, so that the edge thickness of the first lens is ensured, and molding and demolding are facilitated; moreover, the first lens is ridge-fitted outside the lens barrel, so that stray light generated by ridge-fit between the first lens and a second lens is eliminated, and then the quality of imaging is improved.
