A flexible printed wiring board 1 includes a substrate 2, conductor wirings 3 and 4, a coverlay film 5, a jumper wiring 11, and through holes 9 and 10. The conductor wirings 3 and 4 are disposed on a first surface 2a of the substrate 2. The coverlay film 5 covers at least part of the conductor wirings 3 and 4. The jumper wiring 11 electrically connects the conductor wirings 3 and 4 to each other. The through holes 9 and 10 are formed in the substrate 2 and respectively open to the surfaces of the conductor wirings 3 and 4. The jumper wiring 11 is composed of a hardened material of a conductive paste and is formed so that a second surface 2b of the substrate 2 is continuous with respective surfaces 3a and 4a of the conductor wirings 3 and 4 to which the through holes 9 and 10 open. |
