<p>On a front wall of a mold resin (13) sealing a light emitter (12), a direct emission region (18), through which the light emitted from the light emitter (12) directly passes to the outside, and a total reflection region (19), by which the light emitted from the light emitter (12) is totally reflected, are formed. The direct emission region (18) is formed into a shape of a convex lens. A light reflection portion (20) which is made of a concave mirror is provided on the rear face of the mold resin (13). When a part of the light emitted from the light emitter (12) passes through the direct emission region (18), it is affected by the lens to be emitted to the front direction. After another part of the light emitted from the light emitter (12) is totally reflected by the total reflection region (19), it is reflected by the light reflection portion (20) to be emitted to the front direction through the total reflection region (19). <IMAGE></p> |
