A light emitting apparatus includes: a module including a Peltier device with a first face opposite a second face, a supporting member with a principal surface, and a light emitting semiconductor device, and a package housing the module. The supporting member principal surface has a first area that supports the first face of the Peliter device, and a second area adjacent to the first area that supports the light emitting semiconductor device. The supporting member has a circuit board with different levels to which the Peliter device and the light emitting semiconductor device are connected.
