There is a problem that the cost increases accordingly. Conversely, when cost is given priority, if a plastic frame is used as the holding frame, for example, stable accuracy on the order of μm is difficult, and the same holds for the lens side. In particular, eccentricity, falling down, and the like in the group are caused even by a plurality of lenses in the same holding frame, which is a serious problem in a miniaturized lens with high sensitivity.

Since the precision of the lens holding frame and the lens components is not required, the cost can be reduced. According to the second aspect of the present invention, the lens holding frame is positioned and mounted, and then the rounded surface of the uncentered lens inserted into the lens holding portion is chucked from the front and back, and thereafter, the lens outer peripheral surface and the lens holding surface are held. By adhering or caulking the parts with each other, a low-cost and high-precision lens can be held in the lens holding frame even if the lens is not centered.
