Abstract
A submount includes: a support layer; a first graphite layer disposed on the support layer; a first metal layer disposed on the first graphite layer; and a second metal layer disposed on the first metal layer. The first metal layer is thicker than the second metal layer. A first region in which the first metal layer is not disposed is provided at an outer peripheral portion of an upper surface of the first graphite layer. The second metal layer covers the first metal layer and the first region of the upper surface of the first graphite layer.
