The electronic absorbing unit(16) absorbs an electronic wave reflected from a rotor contact of a circuit board to reduce an influence to a resonation of the antenna(17). Thus, the antenna(17) maintains its inherent characteristics at the internal side likewise at the outer side, thereby faithfully performing its role. The electronic absorbing unit(16) absorbs even an electronic wave directing to a human body after being generated from the front side of the mobile phone(10), as well as the electronic wave generated from the antenna(17). An outer face of the bottom portion of the electronic wave absorbing unit(16) is attached on the circuit board, and side walls formed at both sides of the bottom portion have a long hole shape protruded from the surface of the circuit board. A section of the electronic wave absorbing unit(16) makes an angular U-shape. That is, the bottom portion and the side walls make 90° with each other. The antenna(17) is installed in the hole shape electronic wave absorbing unit(16). The entrance of the electronic wave absorbing unit(16) is preferably 90° to 180° centering around the antenna(17) installed in the electronic wave absorbing unit(16).
