PURPOSE:To obtain easily a flat part on which a light travels straight by executing a masking except a designated shape and irradiating a laser beam to a prism lens surface of a prism lens passive reflector. CONSTITUTION:A masking 3 is executed except a designated graphic, and a laser beam is irradiated to a prism lens 4. As a result, since no blur is generated on a part irradiated by the laser beam, it becomes convenient to make a light pass through from the inside. Also, when a light emitting body is placed in a prism lens passive reflector 2, it can be provided with not only a reflecting property but also a light emitting property. |
