Abstract
A lighting device includes a light source, a board, and a light guide. The light source emits light. The board mounts the light source on a mount surface perpendicular to a light emission surface of the light source. The light guide has an incident surface which the light emitted from the light source enters. The incident surface is opposed to the light emission surface. The light guide extends from the incident surface in a direction of the emitted light and is bent toward an irradiated surface of an irradiation target on a way of the light guide. The board is disposed such that an opposite surface of the board opposite the mount surface is opposed to the irradiated surface of the irradiation target.
