The present invention provides small F-measure, wide-angle and compact structure, from the center of the Ministry of the imaging area to the imaging regions of the periphery so far will be able to get a good image of the camera lens, and imaging apparatus equipped with the camera lens. The camera lens (1) in order from the object side substantially from the concave toward the image side of the negative first lens (L1), a positive second lens convex toward the image side (L2), a third negative lens concave toward the image side (L3), biconvex positive fourth lens shape (L4), positive the fifth lens is biconvex shape (L5), a sixth negative lens concave toward the object side (L6) formed. The imaging lens (1) satisfies the conditional formula relating to the radius of curvature (R3) of the object side of the second lens (L2) and the focal length (f) of the whole system (1): R3 / F < 0.
