A method is provided for manufacturing a transformer. The method includes preparing a core, a first coil portion that covers at least part of the core, and a second coil portion that covers a periphery of the first coil portion perpendicular to a central axis of winding of the first coil portion. The first and second coil portions each include a bobbin and a coil wound therearound. The coil of the first or second coil portion is an edgewise coil. The method also includes: screwing the bobbin and coil of the first coil portion with each other, and screwing the bobbin and coil of the second coil portion with each other; and attaching the second coil portion to the outside of the first coil portion perpendicular to the central axis of winding of the first coil portion, and attaching the core to sandwich the first and second coil portions in an axial direction of the first coil portion.
