PURPOSE:To realize a rigid flex printed wiring board which resists against bending even at the contiguous part by forming the protective layers of a flexible printed wiring board and a rigid printed wiring board integrally including its contiguous parts and simultaneously with the formation of protective layer for the rigid flex printed wiring board. CONSTITUTION:A flexible part 3 comprising a flexible printed wiring board is integrated with rigid parts 1, 2 comprising a rigid printed wiring board 8. A protective layer 6 is then formed entirely on the flexible part 3 and the rigid parts 1, 2 including the contiguous part of the rigid printed wiring board 8. Since the step for forming a protective layer is not required in the production of flexible printed wiring board, inner layer step can be simplified. |
