Abstract
A vehicle body-embedded antenna device basically includes a plate-like antenna element, a circuit board and a fixed conductive part. The plate-like antenna element is disposed inside the bathtub-shaped part at the highest possible level therein so as to be substantially parallel to the metal body surface. The circuit board is disposed inside the bathtub-shaped part so as not to overlap the plate-like antenna element as viewed from above. The circuit board has a feeding part connected with the plate-like antenna element. The fixed conductive part is electrically conductive to both the circuit board and the bathtub-shaped part. The fixed conductive part is fixed to a bottom part of the bathtub-shaped part through an attachment hole formed in the bottom part of the bathtub-shaped part.
