Abstract
A light emitting device includes a first semiconductor laser element, a light reflecting member, a base member, and a wire. The base member includes a frame part forming a frame. The frame part has a step portion inside of the frame, a bonding surface bonded to the bottom part, a first inner surface extending below the bonding surface, a second inner surface extending above the bonding surface, a first planar surface defining a planar surface of the step portion on an upper surface side, and a first electrode layer and a second electrode layer electrically connected to each other. The second electrode layer is disposed on the first planar surface. The wire is bonded to the second electrode layer and electrically connected to the first semiconductor laser element. A width of the bonding surface is greater on a first planar surface side than on an opposite side.
