PROBLEM TO BE SOLVED: To provide stable antenna characteristics by suppressing a variation of coupling capacitance according to forming position accuracy of a feeding electrode and a radiation electrode without complicating a structure of a feeding part for a radiation electrode.SOLUTION: A dielectric body 10 includes mutually parallel first principal plane S11 and second plane S12, and a plurality of side faces S21, S31, S22, and S32. At one side face S21 at least of the plurality of side faces of the dielectric body 10, a side face radiation electrode 21 extending from a radiation electrode 11 is formed. A broad electrode part 9f of a feeding electrode is formed so as to face a tip of the side face radiation electrode 21. |
