A photographing lens includes an eccentricity adjusting frame which holds an eccentricity adjusting lens group serving as a part of a photographing optical system of the photographing lens; a lens support frame, an axis of which is coincident with a predetermined optical axis of the photographing optical system, supporting the eccentricity adjusting frame in a manner to allow the eccentricity adjusting frame to move in a plane orthogonal to the predetermined optical axis during an assembly-stage of the photographing lens; and a fixed aperture member having a circular aperture, the fixed aperture member being integrally formed with the lens support frame so that a center of the circular aperture coincides with the axis of the lens support frame.
