A chip antenna 10 includes, inside a rectangular-parallelepiped base 11 having barium oxide, aluminum oxide, and silica as main constituents, a conductor 12 wound in a spiral form along the length direction of the base 11, and an LC parallel resonance circuit 13, which is inserted in the intermediate portion of the conductor 12 and which is connected electrically in series with the conductor 12, and includes, on the surface of the base 11, a power-feeding terminal 14 for applying a voltage to the conductor 12. The conductor 12 is separated into a first conductor 121 and a second conductor 122 by the LC parallel resonance circuit 13. The LC parallel resonance circuit 13 is formed of a coil L1, which is an inductance element, and a capacitor C1, which is a capacitance element, which are connected in parallel.
