<p>A lighting device, for illuminating display designed parts (2a) on a display plate (2), includes at least one light source (7) arranged at a rear side of the display plate (2), and a light guide body (8) having a light guide portion (8A) for guiding the light toward its outer-circumferential portion to output the light toward the display designed parts (2a) through a front surface of the light guide portion (8A). The outer-circumferential portion has an outer-circumferential side wall surface (810) at is outer end. The light guide portion (8A) has at least one projecting portion (81, 82) projecting from the outer-circumferential side wall surface (810). The projecting portion (81, 82) is provided with a reflecting side surface (811a, 822) formed along the outer-circumferential side wall surface (810) so that the reflecting side surface (811a, 822) can reflect the light traveling in the light guide portion (8A) to be outputted through the front surface of the light guide portion (8A).</p> |
