According to a method of manufacturing a light guide of this invention, a shaping member is provided that covers a molding frame. In a releasing step, when the shaping member is lifted up in a direction apart from the molding frame, the light guide is lifted and pulled out from an aperture of the molding frame accordingly. As a result, there is no need to pull out the light guide by conventionally providing a pressing plug on a bottom of the molding frame and pressing the plug in a direction. In addition, there is no need to perform a grinding process to the light guide.
