Abstract
In a lens based on one-group configuration, performance is improved, and a wide angle and a low height are achieved. An imaging lens includes first to third lenses. These first to third lenses are sequentially arranged from an object side to an image surface side without sandwiching air. Each surface of the first to third lenses has an aspherical shape. An imaging element is arranged on the image surface side of the imaging lens. A cover glass is attached on an imaging surface of the imaging element without an air gap. Another lens may be arranged between the imaging lens and the imaging element.
