<p>Provided is an antenna device that can, by just being connected and without requiring cumbersome steps, receive broadcast waves and obtain good reception sensitivity with sufficient gain and over a sufficiently wide frequency range, even if used with wires bundled together. The antenna device has: a power cord (20) that can transmit power; a connection unit (50); a high-frequency signal cable (30) for getting a high-frequency signal from the connection unit (50); and high-frequency cutoff units (40) disposed at two locations along the length of the power cord (20). Part of the power cord (20) between the two high-frequency cutoff units is connected to the connection unit (50), forming an antenna, and the high-frequency signal cable (30) is connected to part of the power cord (20) at the connection unit (50).</p> |
