PROBLEM TO BE SOLVED: To provide a flex rigid wiring board capable of preventing the deformation of a base material which may be easily generated in the vicinity of a bent part, the disconnection of a conductor circuit, the formation of waviness, etc., and excelling in connection reliability. SOLUTION: The flex rigid wiring board is constituted of connecting a flexible board provided with a conductor circuit formed on an insulating base material and a cover layer covering the conductor circuit and having a flexible property and hard rigid boards constituted of forming a conductor circuit on an insulating substrate. In the flex board, a flexible base material formed by impregnating resin into glass cloth and drying it is adopted as the insulating base material of the flexible board, the conductor circuit is formed on one surface of the flexible board, and a dummy pattern is formed on the other surface in the vicinity of the bent part.
