A lighting device is capable of illuminating display designed parts (2a) provided on a display plate (2) and arranged at-least-partially around a center axis (5a). The lighting device includes a light source (7) which is capable of emitting light and is arranged at a rear side of the display plate (2), and a light guide body (8) having at least one light guide portion (80) including an inner portion (80a) and an outer portion (80b), where the inner portion (80a) has a rear side surface (84) for receiving the light from the light source (7) and a front side surface (81) with a curvature for reflecting the light to change a forward-backward direction of the light inputted from the light source (7) toward an outwardly radial direction to guide the light so that diffusion, from a central line (1) passing through the center axis (5a) and the light source (7), of the light traveling through the outer portion (80b) can be suppressed. |
