Abstract
An illumination apparatus includes a light source that emits light, a light guide member that has a base end surface onto which the light emitted from the light source is incident and a tip surface which is an opposite end surface to the base end surface, and guides the light from the base end surface towards the tip surface, and an attachment member that has a light shield property and an opening corresponding to a shape of the light guide member and accommodates the light guide member in the opening. The light guide member is curved so that a distance between the light guide member and the opening is gradually increased towards the tip surface-side in a longitudinal direction of the light guide member.
