Abstract
After an optical element 6, and more preferably both an optical element 6 and an electrical element 7, are mounted on a substrate 1, an upper clad 5 of optical waveguide is formed, covering these elements, and thereby a structure of hermetic seal is achieved through the use of the upper clad 5.
