A vehicle-mounted antenna for a vehicle-mounted information processing
device performs wireless communication within a vehicle between the
vehicle-mounted information processing device located at a rear side of a
veneer plate and another electronic circuit within the vehicle. The
vehicle-mounted information processing device reads data from a medium
inserted via a media insertion opening formed in the veneer plate and
executes various processing based on the read-in data. The
vehicle-mounted antenna is arranged deeper than the media insertion
opening, within a region set if the media insertion opening is extended
in a direction substantially orthogonal with the veneer plate.
