Abstract:
This transformer comprises an outer coil conductor wiring and an inner coil conductor wiring that are disposed in an insulator. The outer coil conductor wiring includes a first outer coil and a second outer coil. A second end of the first outer coil and a second end of the second outer coil are connected to each other. The first outer coil and the second outer coil are wound so as to generate opposing magnetic fluxes when current flows from a first end of one of the first outer coil and the second outer coil to a first end of the other of the first outer coil and the second outer coil. The inner coil conductor wiring includes a first inner coil and a second inner coil. In a plan view, the first inner coil is disposed inside the first outer coil, and the second inner coil is disposed inside the second outer coil.
