PROBLEM TO BE SOLVED: To prevent performance of a dielectric antenna from being deteriorated, in spite of its size being small. SOLUTION: A feeding terminal is provided on a bottom face or a side face of a dielectric material that is formed flat, an antenna strip electrode is formed on the upper face of the dielectric material and the feeding terminal, and the antenna electrode are connected through the inside or the side face of the dielectric material in this dielectric antenna. A ceramics material with a high dielectric constant is employed for a flat dielectric material 1. Then the antenna strip electrodes 2, 2' are formed into a form of a plurality of spirals of different or the same patterns.
