Abstract
A light emitting device includes: a first semiconductor laser element; a second semiconductor laser element; and a light exit surface which emits light from the first semiconductor laser element and the second semiconductor laser element. The first semiconductor laser element is disposed at a position farther than the second semiconductor laser element as seen from a flat surface including a point on a surface of the light exit surface and perpendicular to a light extraction direction.
