PROBLEM TO BE SOLVED: To suppress frequency changes due to antenna mounting dispersion, while maintaining the size of the antenna, and without changing the effective mounting area. SOLUTION: In an antenna device 10A, a part, corresponding to an open end portion 14a of an antenna 14 within a mounting surface 12a of a dielectric board 12, is fixed to a wiring board 16 through a land 22 by e.g. brazing or soldering, and a part, corresponding to a feeding portion of the antenna 14 within the mounting surface 12a of the dielectric board 12, is fixed to a ground electrode 18 by e.g. brazing or soldering. An electrode 24 is formed at a place facing a part (part connected to the mounting surface 12a of the dielectric board 12) of the open end part 14a, and a part of the land 22 of the antenna 14 in the dielectric board 12.
