PROBLEM TO BE SOLVED: To connect an optical waveguide and an optical component easily with low connecting loss and with superior reproducibility. SOLUTION: An optical coupler is a device for optically connecting an optical waveguide 1, which is formed on a baseboard 3, to an optical component 37 with an angle formed with respect to the baseboard 3. The optical waveguide 1 is provided with a hole 1a with an angle formed with respect to the baseboard 3, while an optical waveguide unit 4 is installed attachably and detachably inside the hole 1a. The optical waveguide unit 4 is formed for the purpose of optically connecting to the optical component 37 at one end, and is provided with at least one slant face 38 for converting an optical path at the other end. The optical waveguide unit 4 is inserted into the hole 1a, takes a prescribed position with the slant face 38 or its proximity coming into contact with the bottom of the hole 1a, and connects optically to the optical waveguide 1 through the slant face 38. |
