To make a fluctuation in flange back accompanying a molding error of a central thickness of a front lens smaller.

The photographic lens 10 comprises a first positive lens 11 of a meniscus shape turning its convex surface toward an object side and a second positive lens 12 of a biconcave surface. The image side curved surface of the first positive lens 11 and the image side curved surface of the second positive lens are formed into an aspheric surface shapes. When the ratio of the effective aperture of the photographic lens 10 and the combined focal length of the entire system is denoted as F, the focal length of the first positive lens 11 as f1, the focal length of the second positive lens 12 as f2, the radius of curvature on the object side spherical surface of the first positive lens 11 as R1 and the radii of curvature of the respective surfaces of the second positive lens 12 are denoted as R3 and R4, 5.6≤F<8, f1>f2, 0.39<f/f1≤0.5, 0.15<R1/f<0.19, 1.4<(f/R3)×F≤3.0, R3>|R4| are satisfied, by which the error sensitivity can be reduced.
