The first lens (1) is a spherical meniscus lens which has negative power and whose convex surface faces an object; the second lens (2) is an aspherical meniscus lens which has negative power along an optical axis and has positive power off the optical axis and whose convex surface faces the object side; and the third lens (3) is a lens which has positive power. The Abbe number of the second lens (2) is 30 or less; the ratio between the diagonal length D of an imaging device placed on an image plane of the lens system and the focal length f of the whole of the lens system, f/D, is 0.26 or less; and the ratio between the focal length f3 of the third lens (3) and the focal length f of the whole of the lens system, f3/f, is less than 1.5. This provides a wide angle lens whose lenses can be easily manufactured and whose distortion can be decreased even when a small number of lenses are used.
