An optical element holding device (51) includes a holder (62) having a bearing surface (63) and a clamping member (64) for holding a flange (60a) of a lens (60), and a frame (61) coupled to a barrel (37). The holder holds the lens such that its optical axis (AX') is oriented in the horizontal direction. The holder is arranged such that a plane (P1) passing through its holding position and extending in a direction intersecting the optical axis of the lens substantially passes through the center of gravity (Gc) of the lens. The holder thus arranged stably holds the lens while preventing a moment of rotation from being produced, restrains deformation of optical surfaces of the lens, and maintains satisfactory optical performance. <IMAGE>
