<p>Provided is a seal structure which has a seal member integrally formed on a flexible wiring board without peeling out an insulating layer (top coat) of the flexible wiring board, has excellent sealing performance and can be manufactured at a low cost. The seal structure is composed of a housing wherein the flexible wiring board is inserted through, and the seal member, which is integrally formed with the flexible wiring board and seals a gap between the housing and the flexible wiring board. The flexible wiring board is composed of a base FPC composed of an elastic material, a patterned copper foil and an adhesive layer, a conductive electromagnetic shielding layer formed on the surface of the base FPC, and an insulating layer covering the surface of the electromagnetic shielding layer. The seal member is directly and integrally formed on the insulating layer by using a self-adhesive liquid rubber.</p> |
