れることも少なくない。As shown in FIG. 1, flexible circuit boards conventionally generally include conductors 4, 4, . . . provided between a base film 1 and a cover film 2; , a base film IKM, a metal foil such as aluminum or copper is adhered, and conductors 4.4, . . . are formed by etching, etc., and then conductors 4.4, . When used in conjunction with the cover film 2 (or cover coat K), it provides insulation to the surface of the conductor 4, 4, etc., and a solder resist treatment is applied to the predetermined ends of the base. Utilizing the flexibility of the film 1 and the cover film 2, they are often used as movable wiring components, but recently they are often used as fixed wiring components depending on the object to be mounted.

が保持されるものである。In addition to the above, the present invention provides a structure in which a circuit board shape fixing member having plasticity is attached to at least one of the base film and the cover film, so that the shape deformed during mounting can remain as it is. A flexible circuit board is provided, which will be further described below with reference to the illustrated embodiments. In FIGS. 2 and 3,
6 is a base film, 7. . . . a conductive layer formed on the base film 6 in the same manner as in the past, 8 is a cover film polymerized and bonded to the base film 6 with an adhesive 9, 1
0.10 is a circuit board shape fixing member that is provided between both films 6 and 8 at each side edge and has a plasticity, and is made of metal or synthetic material through the adhesive 9. It is made of resin or the like and formed into a round bar shape as shown in Fig. 5. In this case, when the circuit board shape fixing member 10.10 is made of metal, the adhesive 9 around it is attached to the same member 10.゜It also has the function as an insulating material for ゜10.〇The flexible circuit board with the above structure can be used as a movable wiring component due to the flexibility of the base film 6 and the cover film 8. Due to the plasticity of the circuit board shape fixing member 10.10, it can also be used as a fixed wiring component.For example, when the flexible circuit board is mounted in a substantially B-shape and fixed in that state. As shown in FIG. 5, once the trap is deformed to match the shape of the mounting location, the deformed state is maintained by the plasticity of the circuit board shape fixing members 10, 10.
