Abstract
A wide angle optical lens, an optical lens unit, and an imaging device are small-sized and can secure an attachment space even when space is limited, and can avoid adhesion peeling or the extrusion of an adhesive. Optical lens () has a lens frame receiving surface () on the side of first optical surface (S) having a smaller optical surface diameter than second optical surface (S), and is further provided with an adhesion space forming surface () on the surrounding side of the lens frame receiving surface (). Therefore, it is possible to suppress adhesion peeling even when a smaller size is requested. Furthermore, by securing a larger size for lens frame receiving surface (), it is possible to suppress leakage or extrusion of adhesive from lens frame receiving surface () and thus adherence to first optical surface (S).
