A communication device has a storage, a GPS receiver, a communicator, and a controller. The storage stores a planned travel route. The GPS receiver receives GPS signals. The communicator communicates with the outside. The controller sets an area including the planned travel route as a target area, and when an out-of-area state has begun in which the location of the communication device falls outside the target area, transmits information indicating the location of the communication device as observed when the out-of-area state began to a previously registered transmission destination.
