Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the reflectivity, makes a flexible printed board less noticeable even when the printed board appears in a reflector, and prevent the occurence of cracks resulting from processing.SOLUTION: A flexible printed board 1 has a board body 2 having a base material 3, a conductor circuit 4 formed on a surface of the base material 3, and a cover material 6 laminated on the upper side of the conductor circuit 4 so as to cover the conductor circuit 4. A metallic coating layer 7 having the thickness of 1 to 10 μm is laminated on a surface of the board body 2. The metallic coating layer 7 is formed by adding aluminum particles to a synthetic resin and is provided so as to avoid a light emitting element attachment part 2a of the board body 2.
