Abstract
A main body of an illuminating knob is formed as a base made of a transparent resin. An undercoat layer and a topcoat layer are applied on a peripheral surface of the base. A pattern inside eliminating portion is formed in a shape of an indicating pattern as a marked portion by a laser etching or a partial exfoliation of the topcoat layer on the bottom portion. By passing light from a light source provided inside of the knob through the marked portion, an indication via passing through light is achieved.
