Abstract: An optical waveguide has a clad, a core surrounded by the clad and having an index of refraction larger than an index of refraction of the clad, an incident end face that makes light enter the core; and an exiting end face that makes light exit from the core. Two side faces of the optical waveguide are formed so as to have an angle change. The two side faces are translationally symmetric with each other, or two side faces excluding a portion of the side faces are translationally symmetric with each other.
