PROBLEM TO BE SOLVED: To provide an antenna which can be made compact in size, can achieve the widening of a frequency band and has improved antenna characteristics. SOLUTION: An antenna 1 has: a dielectric layer 112; a first exciting layer 12 on the dielectric layer 112; dielectric layers 113-116 on the first exciting layer 12; a second exciting layer 17 disposed on the first exciting layer 12 while facing it through the dielectric layers 113-116; and a feeder 14 connected to one end of the first exciting layer 12 and one end of the second exciting layer 17. The feeder 14 is held between a first shield layer 12S and a second shield layer 17S. Furthermore, the antenna 1 is equipped with via wiring (13S and 16S) to connect the other end of the first exciting layer 12 and the other end of the second exciting layer 17.
