PROBLEM TO BE SOLVED: To reduce variation of a high frequency transformer, and/or to reduce the leakage inductance.SOLUTION: A high frequency transformer 2 comprises: an annular core 10; and a plurality of cut-annular windings 12. The plurality of cut-annular windings 12 have a discontinuous part in the circumferential direction, respectively, and are arranged radially so that the annular core 10 is located in each ring. The cut-annular winding 12 is formed of a flexible substrate, for example. The plurality of cut-annular windings 12 include a plurality of first cut-annular windings 14 and a plurality of second cut-annular windings 14. One of the primary winding or secondary winding is formed by connecting the discontinuous parts of the plurality of first cut-annular windings 12 by means of a plurality of windings, and the other of the primary winding or secondary winding is formed by connecting the discontinuous parts of the plurality of second cut-annular windings 16 by means of a plurality of windings. |
