Abstract
Abstract A polymer optical waveguide device is provided, wherein a polymer film having an optical waveguide formed therein is sandwiched between two substrates and secured to the substrates with a bonding agent. At least one of the substrates is a substrate having a groove in the inside in which the polymer film can be inserted, the depth of said groove is adjusted in such a manner that the size of the depth of the groove section defined by the two substrates is larger than the size of the thickness of the polymer film, and the polymer film is sandwiched between the substrates at the groove section and is bonded to the substrates with a bonding agent.
