Abstract
A circuit board () is provided with a first rigid part () having a power system electronic component mounted thereon, a second rigid part () having a control system electronic component mounted thereon, and a thin flexible part () connecting the first and second rigid parts to each other. The flexible part () is provided with a plurality of conductive wires () conducted with the electronic components of the first and second rigid parts (). A non-conductive metal pattern () that is a dummy pattern is formed along an outer edge () of the flexible part (). By the non-conductive metal pattern (), the disconnection of the conductive wires () due to cracking is suppressed.
