Abstract
A coil includes a plurality of segment coils. Ends of two corresponding segment coils are electrically connected together via a coupling member or by being fitted together. Each of the plurality of segment coils includes a conductor-exposed portion located close to a connection portion between the corresponding segment coils and to be brought into contact with a probe of a resistance measurement apparatus. When the coil is manufactured, the ends of the plurality of segment coils are electrically connected to the ends of other corresponding segment coils, and electric resistances of connection portions between the ends are measured for each layer of the ends of the segment coils.
