A light emitting device includes semiconductor laser elements, a frame part, a light-reflective member, a step part, metal films, wires, and a first protective element. The frame part surrounds a bottom surface on which the semiconductor laser elements are disposed. The light-reflective member is disposed on the bottom surface inside of a frame formed by the frame part. The step part is formed along a second inner lateral surface of the frame part, and disposed inside of the frame. The metal films are provided on an upper surface of the step part. The wires electrically connect the semiconductor laser elements respectively to the metal films. The first protective element is disposed on the upper surface of the step part and on a light traveling side of the laser light with respect to a plane including an emitting end surface of the first semiconductor laser element.
