1. A motor driving device, comprising:
a wiring board;
a first mounting region on the wiring board, the first mounting region being configured to enable a first circuit component to be mounted therein;
a second mounting region on the wiring board, the second mounting region being configured to enable a second circuit component to be mounted therein;
a first pair of connecting points configured to connect a first connecting wire member, which constitutes a first path through which an electrical current is supplied to the first circuit component, onto the wiring board in a manner so that at least a portion of the first connecting wire member overlaps with the second mounting region; and
a second pair of connecting points configured to connect a second connecting wire member, which constitutes a second path through which an electrical current is supplied to the second circuit component, onto the wiring board in a manner so that at least a portion of the second connecting wire member overlaps with the first mounting region,
wherein
the first pair of connecting points and the second pair of connecting points are arranged outside the first mounting region and the second mounting region,
in a case where the first connecting wire member is connected to the first pair of connecting points, mounting of the second circuit component in the second mounting region is inhibited by the first connecting wire member that overlaps with the second mounting region, and
in a case where the second connecting wire member is connected to the second pair of connecting points, mounting of the first circuit component in the first mounting region is inhibited by the second connecting wire member that overlaps with the first mounting region.
