PROBLEM TO BE SOLVED: To provide an antenna device capable of improving the performance of an antenna, and preventing water from entering an amplifier, and reducing an influence due to the thermal expansion and thermal contraction of a vehicle exterior article.SOLUTION: An antenna device 10 is disposed in a vehicle exterior article such as a spoiler mounted on the outside of a vehicle body 40. An amplifier substrate 14 is fixed to a bracket 16, and configured to amplify and output a radio wave signal received by an antenna element. A bolt 18 for GND is configured to fix the bracket 16 to the vehicle body 40, and to electrically connect the bracket 16 to the vehicle body 40. An amplifier cover 20 is fixed to the bracket 16 to cover the amplifier substrate 14. An elastic member 22 is disposed between the amplifier cover 20 and the vehicle body 40 to cover the outer periphery of the amplifier cover 20, and configured so as to be compressed according as the amplifier cover 20 is pressed against the vehicle body 40. |
