The third lens element is a positive meniscus lens element having a convex surface on the image side. At least one of second to sixth lens elements is made of glass. The fixed focal length lens system satisfies condition (1) below: 0<(L1R2+L2R1)/(L1R2−L2R1)<100  (1) where L1R2 is a radius of curvature of an image-side surface of first lens element, and L2R1 is a radius of curvature of an object-side surface of second lens element.
