PROBLEM TO BE SOLVED: To enable easy and assured connection of a capacitor element to a planar coil pattern formed on a substrate, in a resonant antenna.SOLUTION: A resonant antenna includes a coil element having one end and the other end, and a capacitor element 25 connected between the one end and the other end of the coil element. The coil element 21 is constituted by a planar coil pattern 21A formed on a substrate 52. The capacitor element 25 has a base material sheet 26 composed of a long flexible material and having a first surface and a second surface facing to each other, a first capacitor electrode 27 provided on the first surface of the base material sheet 26, and a second capacitor electrode 28 provided on the second surface of the base material sheet 26. The first capacitor electrode 27 and the second capacitor electrode 28 are connected to the one end 22a and the other end 22b of the coil element 21 with the capacitor element 25 being folded at least one time. |
