An object of the invention is to provide a vehicle-mounted information processing apparatus capable of specifying the position of another vehicle with high accuracy using information related to the distance between another vehicle and an intersection point. The vehicle-mounted information processing apparatus includes: a map information storage unit (11) that stores map information including position information of a road and an intersection point; an inter-vehicle communication unit (4) that acquires various kinds of information using inter-vehicle communication with another vehicle; an another-vehicle GPS information acquiring unit (13) that acquires GPS information related to the position of another vehicle and acquires first reference intersection point distance information related to a distance between another vehicle and a first reference intersection point which is recognized by another vehicle as an intersection point that is in front of another vehicle and is closest to another vehicle, through the inter-vehicle communication unit (4); and an another-vehicle position specifying unit (16) that specifies the position of another vehicle on the basis of the GPS information, the map information, and the first reference intersection point distance information.
