ABSTRACT:
The present invention is directed to an optical waveguide module which is arranged to be free from a breakage of a coupling part of an optical waveguide and optical fibers which are housed in a housing and deviation of an optical axis at this coupling part even though a tensile force is applied to optical fibers. A waveguide board having an optical waveguide is housed in a housing and an optical connector to which bare optical fibers are connected is bonded to an end face of the waveguide board to form a first holding part. An optical fiber conductor and an optical fiber tape are introduced into the housing through a side wall of the housing, and the covering parts of the optical fiber conductor and an optical fiber tape are bonded to the side wall of the housing with a bonding agent to form a second holding part. The bonding strength of the second holding part is determined to be larger than the bonding strength of the first holding part.
