ELECTROMAGNETIC COIL DEVICE AND TRANSFORMER

PROBLEM TO BE SOLVED: To equalize the current distribution in each conductor even when alpha winding is made using a plurality of conductors for the purpose of use at high frequency. SOLUTION: An electromagnetic coil device 1 has a first multilayer coil 3 formed by winding a multilayer straight angle wire 2 so that a direction in which a plurality of straight angle wires 21 to 24 are layered is inward in the diameter direction of the coil, a second multilayer coil 4 formed by winding the multilayer straight angle wire 2 so that a direction in which a plurality of straight angle wires 21 to 24 are layered is outward in the diameter direction of the coil, and a multilayer turning part 5 constructed by twisting the multilayer straight angle wire 2 so that the layering direction is inward in the diameter direction in one end 5A in which the first multilayer coil 3 is connected to the multilayer straight angle wire 2, the layering direction is outward in the diameter direction in other end 5B in which the second multilayer coil 4 is connected to the multilayer straight angle wire 2, and the layering direction is turned from inward to outward in the intermediate portion 5C between the one end 5A and the other end 5B.
