PROBLEM TO BE SOLVED: To provide a lighting fixture with enhanced strength while reducing cost for a casing.SOLUTION: A lighting fixture is provided with an extrusion-molded casing formed in a rectangular tubular shape with four platy parts and both longitudinal open ends, a light source unit, and a reinforcing plate. In either one of the platy parts, slits continuously extending entirely in a length direction is formed. Either one of the platy parts is divided in a width direction. The light source unit includes: a substrate which is provided on an outer wall of either one of the four platy parts, and extends in a longitudinal direction; and a light-emitting element mounted on the substrate. The reinforcing plate is arranged inside the casing, and is in contact with inner walls of at least two opposing platy parts out of the four platy parts. |
