Flexible Printed Wiring Board and Electronic Apparatus

摘要

According to one embodiment, a flexible printed wiring board includes a first conductor layer formed on the first surface of an insulation base, a second conductor layer formed on the second surface of the insulation base, a first insulation layer covering the first conductor layer, and a second insulation layer covering the second conductor layer. The first insulation layer has an opening formed in a position corresponding to a connecting terminal portion to expose the first conductor layer. A metal layer is provided in a region ranging from the connecting terminal portion to a bending presumed portion. The metal layer is positioned behind the opening between the second surface and the second insulation layer to avoid the first conductor layer.
