1. A fixed-focus camera module, suitable for assembly in an electronic device, comprising:
a circuit board;
a photosensitive element, which is conductively connected to the circuit board;
a molded base, wherein the molded base is integrally molded on the circuit board and the photosensitive element, and the molded base forms a light window, so as to provide a light passage for the photosensitive chip through the light window; and
an optical lens, wherein the optical lens is supported on the top side of the molded base and corresponds to the light window formed by the molded base, wherein the circuit board comprises a circuit board substrate and at least one electronic component, wherein the at least one electronic component is electrically connected to the circuit board substrate, wherein the circuit board substrate has a blank side and a flexible board connection side opposite to the blank side, and when the fixed-focus camera module is assembled in the electronic device, the blank side of the circuit board substrate is adjacent to the edge of the electronic device, and wherein the blank side of the circuit board substrate is free of the at least one electronic component;
wherein the optical lens comprises a lens barrel unit and a group of optical lens sheets, and the optical lens sheets are supported in the lens barrel unit, and a bottom of the lens barrel unit is disposed on the molded base;
wherein the width of the lens barrel unit is smaller than the width of the molded base, so as to define an extension space by the optical lens and the molded base, wherein when the fixed-focus camera module is assembled in the electronic device, the extension space is used to receive a display screen of the electronic device;
wherein the lens barrel unit has a stepped portion, wherein the stepped portion is above the molded base and extends inwardly toward an optical axis direction set by the optical lens and is configured to receive at least a portion of the display screen of the electronic device, so as to increase the extension space by means of the stepped portion;
wherein the fixed-focus camera module further comprises a filter element lens holder, wherein the filter element lens holder is disposed on the molded base, and is used for mounting the filter element, and the filter element lens holder has a hollow portion corresponding to the filter element, so that the filter element is held in the light passage of the photosensitive element, wherein the thickness of the filter element lens holder at the blank side is smaller than the thickness of the filter element lens holder at the flexible board connection side;
wherein the optical lens is supported partially by both the filter element lens holder and the molded base, wherein the optical lens has a first bottom side and a second bottom side which are opposite each other, wherein the first bottom side is at the blank side and supported by the molded base, and the second bottom side is at the flexible board connection side and supported by the filter element lens holder.
