To provide an on-vehicle antenna device in which indirect feeding can be performed to a radiation conductor provided on a glass face of a vehicle and which is advantageous to miniaturization, reduction in height and cost.
The on-vehicle antenna apparatus 1 is provided with: the radiation conductor 2 directly patterned on the glass face 52 of the vehicle; a base plate 5 fixed to the glass face 52; a frame body 6 fixed to the base plate 5 by means of screws; a feeding board 7 and a circuit board 8 contained and held in the frame body 6; a connection small board 9 for electrically connecting both boards 7, 8; and a cover 10 covered to the frame body 6, and a pattern forming face 7a of the feeding board 7 is brought close and opposed to the glass face 52 to attain the indirect feeding. The frame body 7 is made of a sheet metal and provided with folded pieces 13 to 16 projected inwardly from side plates 6b to sandwich the circumferential edge part of the feeding board 7 and the circuit board 8 in a plate thickness direction, and receiving parts 17 located at positions of connecting the side plates 6b adjacent to each other and acting like receiving faces at four corners of the circuit board 8.
