PROBLEM TO BE SOLVED: To provide an optical waveguide device that can improve latitude of design without increasing connection loss, in connecting to an optical waveguide formed on a substrate an optical fiber cable guided in a groove formed thereon by anisotropic etching. SOLUTION: In the optical waveguide device 1, in the end of the substrate 10 on which the optical waveguide 12 is formed, there is formed a V groove 111 for the purpose of passive alignment with the optical fiber cable 13, in the V groove forming face SF2 recessed by a prescribed depth d from the surface position of the substrate face SF1 on which the optical waveguide 12 is formed.
