PROBLEM TO BE SOLVED: To provide a high-performance imaging lens which offers a wide view angle, a large aperture, compactness in terms of total lens length, total lens thickness, and lens diameters, sufficiently reduced aberrations, and resolving power compatible with high-pixel image sensors.SOLUTION: An imaging lens comprises a plurality of lenses L1-L7. When two adjacent lenses are spaced apart and facing each other, an air space between an image side surface of an object side lens and an object side surface of an image side lens is called an air lens, and the image side surface of the object side lens designated as an object side surface of the air lens and the object side surface of the image side lens designated as an image side surface of the air lens define a shape of the air lens. Both an air lens between a first lens L1 and a second lens L2 which are located on the most object side in the imaging lens and an air lens between a sixth lens L6 and a seventh lens L7 which are located on the most image side are double-convex shaped. |
