PROBLEM TO BE SOLVED: To provide a stacked helical antenna whose frequency reduction is easy. SOLUTION: The stacked helical antenna is equipped with: a plurality of dielectric layers arranged by being stacked; a plurality of first radiation electrodes arranged on any of first surfaces of the plurality of dielectric layers; a plurality of second radiation electrodes arranged on any of second surfaces of the plurality of dielectric layers; a plurality of connection parts for connecting edges of the plurality of first radiation electrodes with edges of the plurality of second radiation electrodes to constitute a helical electrode with the plurality of first, second radiation electrodes; and a first non-supplied electrode which is arranged on a third surface to be boundary of any of the plurality of dielectric layers between the first, second surfaces and is not connected to the helical electrode.
