摘要： A transformer includes a stacked structure in which a plurality of coils is stacked through insulation layers. The stacked structure includes: a primary coil stacked layer including a plurality of primary coil layers connected in parallel with one another; and a secondary coil stacked layer including a plurality of secondary coil layers connected in parallel with one another. One of the primary coil layers is disposed as an outermost layer in the stacked structure, and another is disposed between at least two layers of the plurality of secondary coil layers. The primary coil layer includes a plurality of primary coils connected in parallel with one another. The secondary coil layer includes one or more secondary coils thicker than the primary coil.
