Document Type and Number:
Japanese Patent JP7067458
Kind Code:
B2
Abstract:
A coil includes a plurality of segment coils (30, 30i, 30o). Ends (T) of two corresponding segment coils (30, 30i, 30o) are electrically connected together via a coupling member (35, 35B, 35C) or by being fitted together. Each of the plurality of segment coils (30, 30i, 30o) includes a conductor-exposed portion (N) located close to a connection portion between the corresponding segment coils (30, 30i, 30o) and to be brought into contact with a probe of a resistance measurement apparatus. When the coil is manufactured, the ends (T) of the plurality of segment coils (30, 30i, 30o) are electrically connected to the ends (T) of other corresponding segment coils (30, 30i, 30o), and electric resistances of connection portions between the ends (T) are measured for each layer of the ends (T) of the segment coils (30, 30i, 30o).
