PROBLEM TO BE SOLVED: To provide a compact image capturing lens which offers a larger aperture, good correction for various aberrations, and a seven-lens configuration.SOLUTION: An image capturing lens 10 includes a positive first lens L1 having a convex surface on the object side, a negative second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5, a sixth lens L6, and a negative seventh lens L7 having an object-side surface which is concave near an optical axis AX, in order from the object side, and satisfies a conditional expression: 1.5<ET2/CT2<3.0...(1), where a value CT2 represents a center thickness of the second lens L2 and a value ET2 represents an edge thickness of the second lens L2. Here, the edge thickness of the second lens L2 is defined as thickness in the optical axis direction at a position of the lesser of an effective diameter of an object-side surface S21 and that of an image-side surface S22 of the second lens L2. |
