| 发明名称 | Circuit board | ||
| 摘要 | A circuit board prevents breakage at a boundary between a rigid region and a flexible region and includes a body including stacked flexible sheets, and rigid regions and a flexible region more flexible than the rigid regions. A circuit is defined by a conductor provided in the body. In the flexible region on a principal surface of the body, grooves are arranged to be in contact with boundaries between the flexible region and the rigid regions and to extend along the boundaries. | ||
