PROBLEM TO BE SOLVED: To provide an antenna device and a reception device that can reduce the loss at a terminal joint portion and implement high reception performance.SOLUTION: A reception device includes an audio signal plug 40 connected to a jack unit 22, and an audio signal transmission cable 50 for transmitting an audio signal. One terminal of the plug 40 and one line 613 of the transmission cable 50 are connected to form an antenna signal line LANT. High frequency cutoff portions 621, 622 having high-frequency cutoff functions are connected to other terminals than terminals for forming antenna signal lines of the plug 40 connected to lines 611, 612 other than a line forming an antenna signal line of the transmission cable 50, the jack portion 22 is mounted on a substrate 24, the arrangement region of the jack portion 22 of the substrate 24 is formed as a non-conductive region having no conductive line, and connection terminals and connection lines to be connected to the respective terminals of the plug 40 are formed on the substrate around the arrangement region.SELECTED DRAWING: Figure 2 |
