摘要:
Provided is a seal structure which can reduce the thickness of an electronic device, can be easily assembled and disassembles, and can exhibit an excellent seal performance. Thus, the seal structure for an electronic device, which seals a gap between a flexible wiring substrate inserted to a through-hole provided in a case member of an electronic device and the through-hole, is comprised of an annular gasket composed of a rubber elastic material, a part of which is integrally molded with the flexible wiring substrate, and a retainer plate for retaining the gasket in conjunction with the case member.
