PURPOSE: To make it possible to bend a printed wiring board flexibly in a part thereof by electrically and partly connecting first and second boards which are formed of a plurality of printed substrates in a layer state by means of freely bendable flexible core material. CONSTITUTION: This board consists of a first board 6 and a second board 7 which are formed of a plurality of printed substrates and are connected with each other, and it is provided with a freely bendable flexible core material 1 connecting electrically a part of the board 6 with a part of the board 7. The material 1 is represented by a polyimide film. A continuity part 3 connects every layer electrically and individually, and a copper foil pattern 4 operates as continuity wiring between the respective layers. In addition, a cover film 5 protects the breakage of the pattern 4 in a flexible part between the board 6 and a rigid part 2 of the board 7. |
