Claim:
An image taking lens comprising: an aperture, a first lens, and a second lens, the aperture, the first lens and the second lens arranged in this order from an object side to an image side, wherein the first lens has a positive power and a meniscus shape with a convex surface facing an object and a concave surface facing an image, the second lens has a positive power with a convex surface facing the image, and the first lens and the second lens satisfy the following formulae (1) and (2): 0.40 <R 1 /R 2<0.65 (1) 0.33 <d 3 /F< 0.50 (2) where R 1 : radius of curvature of the convex surface of the first lens facing the object; R 2 : radius of curvature of the concave surface of the first lens facing the image; d 3 : center thickness of the second lens; and F: focal length of the entire image taking lens.
