    • An optical element combination structure in which an optical fiber and an optical waveguide are combined with each other and which can reduce fluctuation of coupling loss due to a change in environmental temperature is provided. The present invention relates to an optical element combination structure in which an optical fiber and an optical waveguide are combined with each other. An optical element combination structure according to the present invention 1 comprises an optical fiber 2 and a substrate 6 on which an optical waveguide 4 is formed. The substrate 6 has a V-shaped cross-sectional groove 8 formed so that the optical fiber and the optical waveguide are aligned with each other, and a recess 10 formed on a waveguide side relative to the groove 8. The optical fiber is secured to the V-shaped cross-sectional groove 8 with an adhesive 22. A tip 18 of the optical fiber 2 protruding into the recess 10 and the optical waveguide 4 are coupled to each other with a coupling agent with which the recess and a space between the optical fiber and the optical waveguide are filled.
