ABSTRACT:
A chip antenna includes a main body and a pedestal. The main body is provided with a rectangular-parallelopiped base member with a relative dielectric constant of about 6.0 having barium oxide, aluminum oxide, and silica as main components; a conductor wound helically inside the base member in the longitudinal direction of the base member; a power-feed terminal formed on a surface of the base member, for applying a voltage to the conductor; and an open terminal formed on a surface of the base member. The pedestal is provided with a base member made from a glass epoxy resin having a relative dielectric constant of about 4.8; and external electrodes extending from opposing ends on surfaces of the base member toward adjacent side faces. The power-feed terminal and the open terminal of the main body are electrically and mechanically connected to the external electrodes of the pedestal by soldering, respectively.
