A lens array includes: an input-lens collective body, which is a collective body of input lenses each having a different optical power in a first direction and in a second direction orthogonal to the first direction, the input lenses being aligned along the second direction for which the input lenses have a larger optical power; and an output-lens collective body, which is a collective body of output lenses each having a different optical power in the first direction and in the second direction orthogonal to the first direction, the output lenses being optically opposed to the input lenses, and being aligned along the second direction. Respective lens dimensions of the input lenses are defined so that the input-lens collective body forms a predetermined irradiated region in the irradiated plane by a collection of irradiated areas of light irradiated from the lens array. Positions of respective lens protruding end portions of the output lenses are defined so that the respective irradiated areas of the output lenses correspond to any one of the irradiated areas which area respectively formed at different positions, and at least a portion of each of the irradiated areas overlaps with at least a portion of the adjacent irradiated areas.
