Abstract
An antenna device used for a UHF tuner or the like, which comprises a combination of an antenna coil formed of single-covered wire with an insulator covering the antenna coil. The insulator is dividedly molded into a coil containing member having an antenna coil containing recess and a terminal member having a pair of antenna terminals and a resistor containing recess, a fitting portion to be fitted between the coil containing member and the terminal member is provided, and at the terminal member a cover for closing an opening at the coil containing recess. The coil containing member containing the antenna coil in the coil containing recess and the terminal member containing a resistor in the resistor containing recess are integrally connected by press-fitting of the fitting portion and the antenna coil is housed in the insulator, thereby obtaining the insulating property equivalent to a double covered wire without deforming the the coil during or after the assembly of the antenna device.
