A waveguide package and a method for manufacturing the same are disclosed. The waveguide package includes a package structure including a waveguide opened toward one side surface of a substrate, a semiconductor chip mounted on one surface of the package structure and configured to output an electrical signal to the waveguide. Since an interior of the waveguide is filled with air, electrical loss of the waveguide is minimized. The cavity is formed by processing the substrate made of photosensitive glass. Accordingly, the waveguide may be accurately formed. An electronic circuit may also be formed at the waveguide package. Accordingly, it may be possible to provide a waveguide package enhanced in degree of integration.
