Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce undesired radiation.SOLUTION: A secondary winding N2 of a choke transformer T1 is wound to cover the entire of a primary winding N1, one terminal of which is connected to ground and the other terminal is opened. Since the one terminal of the secondary winding N2 covering the primary winding N1 is connected to the ground and the other terminal is opened, the secondary winding N2 functions as an electromagnetic shield. Thus, undesired radiation can be reduced.
