An image taking lens LA comprises an aperture S1, a first lens L1 and a second lens L2 which are arranged in this order from an object side to an image side. The first lens L1 has a positive power and a meniscus shape with a convex surface facing an object; and the second lens L2 has a positive power with a convex surface facing an image. The first lens L1 and the second lens L2 satisfy the following formulae (1) and (2): 0.30<R1/R2<0.65  (1) 0.30<d3/F<0.50  (2) This image taking lens formed of the two lenses is small in size and has a high optical performance, in which the entire image taking lens has a short focal length.
