Abstract
A lens array includes a first lens row including first lenses arranged in a first direction, a second lens row including second lenses arranged in a direction substantially parallel with the first direction, a first boundary being a boundary between the first lenses adjacent to each other, a second boundary being a boundary between each of the first lenses and the second lens adjacent to the first lens, and a first join portion where the first boundary and the second boundary join each other. At the first joint portion, the first boundary and the second boundary contact each other with no step as seen in a plane that is substantially orthogonal to the first direction.
