To provide an optical waveguide member that is capable of restraining deterioration of an optical signal, and omitting a process of high-precision finishing of an outer surface area on which light is emitted, when a connection is made with an external optical component.
The optical waveguide member 10 comprises a first clad layer 12 and a second clad layer 14, which are jointed together in a laminated manner, and a core layer 16 which is formed between the first clad layer 12 and the second clad layer 14. An output edge face 20 of the core layer 16, which emits a light L, is disposed next to a jointing face 22 of the first clad layer 12 and the second clad layer 14, and is coated by the first clad layer 12. The first clad layer 12 transmits the light L, emitted from the output edge face 20 of the core layer 16, and on its outer surface, an outputting face 24 which outputs the transmitted light L outward is formed. The jointing face 22 of the first and second clad layers is disposed, at a position such that it does not intersect with the transmitted light L emitted from the output edge face 20.
