<P>PROBLEM TO BE SOLVED: To provide a flexible printed wiring board subjected to folding in which opening (peeling of a folded portion) of the flexible printed wiring board can be prevented by relaxing spring-back of the flexible printed wiring board effectively, and to provide an electronic circuit module where an electronic apparatus is mounted on the flexible printed wiring board, and an electronic apparatus including the electronic circuit module. <P>SOLUTION: A flexible printed wiring board 10 comprises a substrate 11, a conductive layer 12 including circuit wiring 12a laminated on the substrate 11, and an insulation layer 13 laminated on the conductive layer 12. The flexible printed wiring board 10 is provided with a folding portion 14 which is folded from one surface to the other surface in order to be affixed to the other surface in surface contact state. The folding portion 14 is provided with at least two folding wires 14a intersecting the folding direction perpendicularly. <P>COPYRIGHT: (C)2012,JPO&INPIT |
