Abstract
A multi-spiral element includes a group of spiral conductive lines arranged so as not to cross each other so that the spiral conductive lines are substantially rotationally symmetric with respect to a predetermined point on a dielectric substrate. A plurality of conductive lines in the group of spiral conductive lines have external peripheral ends aligned at a substantially straight line substantially orthogonal to the group of spiral conductive lines. The external peripheral ends of each of the plurality of conductive lines in the multi-spiral element are connected to respective ends of a straight-line-group element having a group of parallel straight conductive lines. A resonator includes the multi-spiral elements functioning as capacitors for accumulating a charge, and the straight-line-group element functioning as an inductor.
