Title: Optical device and method of manufacturing optical device including transparent member between optical waveguide core and optical waveguide insertion hole

Abstract: An optical device includes a connector configured to provide a hole, an optical waveguide provided with a core and a clad equipped on an outer periphery of the core and configured to have a refractive index smaller than a refractive index of the core, a first transparent member configured to make contact with a core end face of the optical waveguide, and a second transparent member configured to make contact with a hole bottom of the optical waveguide insertion hole, wherein a contact area of the second transparent member and the hole bottom of the optical waveguide insertion hole is larger than a contact area of the core and the first transparent member.
