PURPOSE: To provide a packaging strucrue for an optical waveguide and optical fiber which maintains initial characteristics over a long period of time even at and under a high temp. and high humidity and withstands vibrations and impact, and a packaging method.
CONSTITUTION: An end face 4 of an optical waveguide substrate 1 and an end face 5 of an optical fiber arranging member 2 housing the optical fiber 3 are adhered via an adhesive 6 in such a manner that the optical waveguide 13 and the optical fiber 3 are optically coupled at the time of coupling these two end faces. The surface of the adhesive 6 is coated with an SiO2 film 7. As a result, the moisture in the outdoor air is shut off and physical and chemical stability is attained, and the adhesive 6 is protected. Therefore, the adhesion property is maintained over a long period of time and the characteristics at and under the high temp. and high humidity are greatly improved.
