Abstract
Provided is a semiconductor optical device with light extraction efficiency or light collecting efficiency higher than that of conventional devices and with a reduced peeling ratio of a wiring electrode portion, and a method of manufacturing the same. In the semiconductor optical, a wiring electrode portionis provided on a surface of a semiconductor layerthat serves as a light emitting surface or a light receiving surface, the line width Wof the wiring electrode portionis 2 μm or more and 5 μm or less, the wiring electrode portionhas a metal layeron the semiconductor layerand a conductive hard filmon the metal layer, and the conductive hard filmis harder than the metal layer
