1. An antenna device comprising:
a conductive ground conductor plate;
a plate-shaped radiating element disposed without being in contact with the ground conductor plate;
a feeding line including a conductor and a shield member that surrounds the conductor, the shield member being connected to the ground conductor plate;
a conductive feeding element that includes a facing plate portion that faces the radiating element with a dielectric layer provided therebetween, and is connected to the conductor;
a positioning member with which the radiating element and the facing plate portion are positioned;
a first positioning surface formed in the positioning member, the radiating element being fixed to the first positioning surface while being in surface contact with the first positioning surface; and
a front surface recess portion formed in the positioning member and being a recess formed in a part of the first positioning surface, wherein
the facing plate portion is contained in the front surface recess portion.
