A transformer includes a multilayer board including insulation layers stacked in a thickness direction, a primary coil provided on at least one of the insulation layers, and a secondary coil provided on at least one of the insulation layers. The primary coil includes first sub coils electrically connected in series to each other, and second sub coils electrically connected in series to each other. Surfaces of the plurality of insulation layers constitute layer planes of the multilayer board. At least two of the first sub coils are provided on layer planes out of the layer plane different from each other. At least two of the second sub coils are provided on layer planes out of the layer planes different from each other. An average of positions of the first sub coils in the thickness direction is aligned with an average of positions of the second sub coils in the thickness direction.
