To facilitate securing of a space for installing an enclosure for mounting an amplifier.SOLUTION: An antenna device comprises a glass antenna for the window glass of vehicle, and an enclosure for connection with the glass antenna. The glass antenna has a first electrode for electric supply, a second electrode for electric supply, a third electrode for earth, a first antenna for connection with the first electrode, and a second antenna for connection with the second electrode. The enclosure has a first terminal for electric supply for connection with the first electrode, a second terminal for electric supply for connection with the second electrode, a third terminal for earth for connection with the third electrode, a first amplifier for connection with the first and third terminals, and a second amplifier for connection with the second and third terminals. The first antenna includes a first folding element folded to open in the horizontal direction, and the second antenna includes a second folding element folded to open while facing the first folding element.SELECTED DRAWING: Figure 1
