Abstract
A manufacturing method of an optical waveguide, the optical waveguide including a first clad layer; a core layer formed on the first clad layer and configured to propagate light; a second clad layer formed on the first clad layer so as to cover the core layer; and a light propagation direction changing part configured to change a propagation direction of the light propagating in the core layer; the manufacturing method of the optical waveguide includes the steps of forming a concave part penetrating the first clad layer and the core layer; and inserting the light propagation direction changing part into the concave part so that a light propagation direction changing surface of the light propagation direction changing part forms a predetermined inclination angle to a predetermined reference plane.
