PROBLEM TO BE SOLVED: To provide an antenna device receiving broadcast waves with sufficient gain in a sufficiently wide frequency band even if wire materials are bundled and used only by connection without requiring complicated time and effort, and acquiring excellent reception sensitivity. SOLUTION: The antenna device includes: power supply cords 21, 22; an antenna substrate part 100 on which a first antenna element 110 and a second antenna element 120 are formed; a high frequency signal cable 30 for extracting high frequency signals from the antenna substrate 100; and high frequency interrupting parts 41, 42 disposed on two sites of the length direction of the power supply cords 21, 22. In the power supply cords 21, 22, a part between the two high frequency interrupting parts 41, 42 is connected to the first antenna element 110 to form a first antenna 11. The high frequency signal cable 30 is connected to the first and second antenna elements 110 and 120. In the antenna substrate part 100, the first and second antenna elements 110 and 120 form a second antenna 12. COPYRIGHT: (C)2011,JPO&INPIT
