PROBLEM TO BE SOLVED: To provide an LED lighting fixture capable of improving incident efficiency by preventing relative positional deviation between an incident end surface of a light guide plate and an LED chip.SOLUTION: An upper LED light emitting part accommodated in a fixture body irradiates an incident end surface opposing with respect to a light source of the LED light emitting part with light. An upper light guide plate emits light from a plane surface crossing with respect to the incident end surface. At the incident end surface, a protrusion part protruding in a thickness direction of the upper light guide plate is provided. Also, the upper LED light emitting part has a circuit board and an upper holder 31 for fixing the circuit board. At the upper holder 31, at least one pair of protrusion strip parts is provided at positions with a predetermined distance apart so as to sandwich the protrusion part. Therefore, as the protrusion part is sandwiched by the pair of protrusion strip parts, the protrusion part is restricted for movement along a direction parallel with the longitudinal direction of the incident end surface with respect to the upper holder 31. |
