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