Arrangement of a light guide plate and a dial, wherein the light guide plate comprises: a light emitting section that is arranged so as to overlap the dial which is provided with translucent designs; a light guide section that is connected to the light emitting section and has a light incidence surface on which light of a light source is incident; and a reflective section that reflects light, which is guided to the light emitting section by the light guide section, toward a first surface facing the dial of the light emitting section, and is provided on a second surface facing the first surface of the light emitting section, wherein the reflective section is configured by plural reflective bodies which are arranged at intervals and plural reflective surfaces which are arranged between the plural reflective bodies, the reflective body includes plural striated portions and the reflective body is configured by arranging the plural striated portions to be in contact with each other in a width direction thereof, the striated portions are formed on the second surface and are arranged in a direction intersecting the traveling direction of incident light, which can travel through the light emitting section, so as to be in contact with each other in the width direction of the striated portions, the striated portions are plural ridges with a wedge cross-section or plural furrows having a V-shape in cross-section, the incident light can pass through the striated portions while the light can be refracted toward the first surface, and then can be reflected in a direction perpendicular to the dial, wherein, one or a plurality of auxiliary striated portions are provided only in a low-intensity portion of the reflective body so as to be in contact with the striated portions of the reflective body in a width direction thereof, and the low-intensity portion is formed such that the width thereof is gradually reduced in a radial direction of the light guide plate and is arranged at a position where an intensity of light traveling through the light emitting section is lower than a predetermined reference value. a light emitting section that is arranged so as to overlap the dial which is provided with translucent designs; a light guide section that is connected to the light emitting section and has a light incidence surface on which light of a light source is incident; and a reflective section that reflects light, which is guided to the light emitting section by the light guide section, toward a first surface facing the dial of the light emitting section, and is provided on a second surface facing the first surface of the light emitting section, wherein the reflective section is configured by plural reflective bodies which are arranged at intervals and plural reflective surfaces which are arranged between the plural reflective bodies, the reflective body includes plural striated portions and the reflective body is configured by arranging the plural striated portions to be in contact with each other in a width direction thereof, the striated portions are formed on the second surface and are arranged in a direction intersecting the traveling direction of incident light, which can travel through the light emitting section, so as to be in contact with each other in the width direction of the striated portions, the striated portions are plural ridges with a wedge cross-section or plural furrows having a V-shape in cross-section, the incident light can pass through the striated portions while the light can be refracted toward the first surface, and then can be reflected in a direction perpendicular to the dial, wherein, one or a plurality of auxiliary striated portions are provided only in a low-intensity portion of the reflective body so as to be in contact with the striated portions of the reflective body in a width direction thereof, and the low-intensity portion is formed such that the width thereof is gradually reduced in a radial direction of the light guide plate and is arranged at a position where an intensity of light traveling through the light emitting section is lower than a predetermined reference value.
