To provide a light-emitting device that improves light extraction efficiency, uniforms luminance and heat generation in a light-emitting region of an active layer, and suppresses variation in operating voltage and lifetime between elements.

A light-emitting device according to the present invention comprises: a semiconductor stacked structure including a light-emitting layer; an upper electrode; an interface electrode; a current blocking layer; a reflective layer reflecting light transmitted through the current blocking layer toward a surface side of the semiconductor stacked structure; a supporting substrate with conductivity; and an external electrode. The upper electrode has a circular portion with a predetermined diameter and a plurality of branch portions with a predetermined line width. The interface electrode has a plurality of second contact electrodes that have a predetermined line width and are formed in a line shape. Each of the second contact electrodes is arranged between the branch portions when the light-emitting device is viewed from the top. The distance between each second contact electrode and each branch portion in a plan view is substantially constant.
