Abstract: A light emitting element array includes: a light emitting element group that includes plural light emitting elements; and plural lenses that are provided, corresponding to the plural light emitting elements, on a light emitting surface side of the plural light emitting elements, and that deflects light emitted from the plural light emitting elements according to a positional relation with the plural light emitting elements. Distances between central axes of light emission of the plural light emitting elements and central axes of the plural lenses corresponding to the plural light emitting elements increase from a center side of the light emitting element group toward an end side of the light emitting element group, and a degree of change in the distances decreases from the center side of the light emitting element group toward the end side of the light emitting element group.
