<p>A lens array includes: at least one lens including a first lens surface and a second lens surface. The first lens surface is formed to tilt at a predetermined tilt angle with respect to the second lens surface. The first lens surface is formed to be eccentric by an eccentric distance in such a direction that the optical axis of the second lens surface and an optical axis of the first lens surface intersect on a side of the first lens surface.</p> |
