Abstract:
1. A light-emitting device comprising: a base; a fusion-bonding material layer formed on a first surface of the base; and a semiconductor light-emitting element including a waveguide fixed on the first surface, an axis line of the waveguide is inclined at and angle of θ wherein at least one alignment mark is formed in the fusion-bonding material layer, the alignment mark having an axis line of the alignment mark that is an extension direction of the alignment mark or a straight line connecting two of the alignment marks, the axis line of the alignment mark being aligned at an angle relative to an axis line of the base, wherein the alignment mark is aligned at an angle θ wherein the fusion-bonding material layer has a laminate structure including a first fusion-bonding material layer and a second fusion bonding material layer formed in order from the first surface side, and wherein the alignment mark is configured from an opening formed in the first fusion-bonding material layer that exposes a portion of the second fusion-bonding material layer underneath.
