PROBLEM TO BE SOLVED: To provide a luminaire which avoids light emission of a light guide body becoming dark when air bubbles generate in the light guide body by a core layer peeling from a protective layer.SOLUTION: A luminaire includes: a light emitting member 7 which incorporates a light source 8; a light guide body 3 which guides the light from the light source 8 entering from an incident surface which is an end surface 31a in the longitudinal direction; and a storage body 6 which stores the light emitting member 7 and the light guide body 3. The light guide body 3 includes a cylindrical core layer 3a and a protective layer 3b for coating the periphery of the core layer 3a, and also, a terminal 31b of the light guide body 3 is inserted in the light emitting member 7. At the terminal 31b of the light guide body 3, a protective layer notch part 33 in which the protective layer 3b is removed is formed, and a terminal 3aa of the core layer 3a is exposed.SELECTED DRAWING: Figure 9
