Abstract: A positive electrode side input loop line (10a) and a positive electrode side output loop line (10b), and a negative electrode side input loop line (11a) and a negative electrode side output loop line (11b) form two sets of coupling loops, and the loop lines of the two sets have the same winding direction, and have the same loop sizes of and relative relationship between the loop lines. A capacitor (3) is connected in series between the positive electrode side input loop line (10a) and the negative electrode side input loop line (11a).
