Abstract
A transformer which has a core, a wire for a primary coil and two wires for a secondary coil. The wire for a primary coil and one of the wires for a secondary coil are wound around a body of the core together, that is, are bifilar-wound. The other wire for a secondary coil is single-wound around the bifilar-wound wires. The two wires for a secondary coil are connected in series to form a secondary coil, and the wire for a primary coil forms a primary coil by itself.
