Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a structure in which troubles are prevented from occurring in wire connection onto a belt-like wiring conductor, in a light source unit in which a plurality of belt-like wiring conductors are formed in parallel on a substrate, a plurality of LED elements are arranged on the belt-like wiring conductor, each LED element soldered onto the same belt-like wiring conductor is electrically connected to the neighboring belt-like wiring conductor via a wire, and the LED element is arranged on the substrate in a zigzag shape as a whole.SOLUTION: In the same belt-like wiring conductor, an interception groove is formed between neighboring LED elements, a non-outflow region is formed in which solder is prevented from flowing out between the neighboring LED elements, and wire connection is performed in the non-outflow region.
