    Abstract: A chip antenna in which correct evaluation and inspection of a conductor can be performed regardless of the state of grounding. The chip antenna has a rectangular-prism-shaped substrate formed of a dielectric material comprising, e.g., barium oxide, aluminum oxide and silica. A copper or copper-alloy conductor is spirally wound within the substrate in the longitudinal direction. A feeding terminal for applying a voltage to the conductor and a free terminal are disposed on the surfaces of the conductor. One end of the conductor is attached to the feeding terminal, while the other end is connected to the free terminal.
