Abstract
An imaging lens is provided in which a total angle of view is 150 degrees or more, and which exhibits a high-image quality, is compact, is inexpensive, and keeps a stable quality under a harsh environment in an on-board camera or the like. An imaging lens includes a first lens having a negative refracting power and having a meniscus shape in which a convex surface is directed toward an object side; a second lens having a negative refracting power and having a meniscus shape in which a convex surface is directed toward the object side; a third lens having a positive refracting power and having bi-convex shape; an aperture stop; a fourth lens having a positive refracting power and having a bi-convex shape; a fifth lens having a negative refracting power and having a bi-concave shape; and a sixth lens having a positive refracting power and having a bi-convex shape, the first lens, the second lens, the third lens, the aperture stop, the fourth lens, the fifth lens, and the sixth lens being arranged in order from the object side to an image surface side. Thus, the imaging lens includes six groups and six sheets of independent lenses as a whole, has a total angle of view of 150 degrees or more, and fulfills predetermined conditional expressions.
