Patent ID: 8515313

Claim:
An illuminating device comprising a light-emitting element mounted on a base material, and a light-guiding member for guiding light from the light-emitting element to an irradiation target, the irradiation target being illuminated with the light transmitted through the light-guiding member, wherein the light-guiding member has an extending portion that extends from a surface of the base material on which the light-emitting element is mounted to a side end portion of the base material so as to cover the side end portion of the base material, and further comprising a reflecting member that reflects light emitted from the light-emitting element and transmitted through the light-guiding member, thereby illuminating the irradiation target, wherein the light-emitting element and the reflecting member are arranged so as to sandwich a path through which light reflected by the irradiation target passes, and the light-guiding member is disposed on a light-emitting element side, and light guided through the extending portion of the light-guiding member and emitted from the extending portion is reflected by the reflecting member and illuminates the irradiation target.
