<p>The present invention relates to an antenna device whereby there can be provided an antenna device which can receive broadcast waves with a sufficiently wide frequency band and sufficient gain just by connecting wire material even if used bundled without complicated efforts, and can obtain suitable reception sensitivity. This antenna device includes a power supply cord 20 which can transmit power, a connecting portion 50, a high-frequency signal cable 30 for extracting a high-frequency signal from the connecting portion 50, and a high-frequency blocking portion 40 disposed in two places in the length direction of the power supply cord 20, and with the power supply cord 20, a portion between the two high-frequency blocking portions is connected to the connecting portion 50 to form an antenna, and the high-frequency signal cable 30 is connected to a portion of the power supply cord 20 at the connecting portion 50.</p> |
