Abstract: There are provided methods of inspecting an optical waveguide including inspecting the degree of curvature of a light reflecting surface formed in a core of the optical waveguide, and of manufacturing an optical waveguide using the same. In the method of inspecting an optical waveguide, light enters the core of the optical waveguide via a connection surface in a second end portion of the core, to reflect from light reflecting surfaces in a first end portion of the core and to exit the optical waveguide, and the exiting light is imaged by a camera. Then, the brightness of the exiting light is measured by determining the brightness of the obtained image. The degree of curvature of the light reflecting surfaces decreases as the measurement value of brightness increases. Thus, an optical waveguide having a brightness greater than a reference value has light reflecting surfaces which are nearly flat.
