Abstract
The number of conductor members in a first conductor member group and the number of conductor members in a second conductor member group are equal to each other and are odd numbers. An inner terminal of each conductor member is displaced from an outer terminal of the same conductor member by 90 degrees with respect to the circumferential direction of the corresponding conductor member group. Each outer terminal of the first conductor member group is displaced from a corresponding one of the outer terminals of the second conductor member with respect to the circumferential direction of the first conductor member group.
