Abstract
An antenna device is mounted on a vehicle body. A distal end of an antenna element is attached to an antenna base. The antenna base is provided with a conductive screw projection electrically connected with the antenna element and inserted into a hole formed in the vehicle body, and a first insulative member mounted on an outer face of the vehicle body to electrically insulate the screw projection from the vehicle body. A conductive washer is disposed inside the vehicle body such that the screw projection is inserted therethrough. A conductive nut is disposed inside the vehicle body to be screwed to the screw projection to form a conductive path from the antenna element and an electric equipment disposed inside the vehicle. A second insulative member is disposed inside the vehicle body to electrically insulate the screw projection from the washer, and to electrically insulate the nut from the washer.
