PROBLEM TO BE SOLVED: To provide a navigation device capable of showing quickly the correct position and direction of a vehicle, when the vehicle conveyed in the non-self-traveling state reaches a conveyance destination. SOLUTION: The vehicle position is estimated from a detection result showing the absolute position by an absolute position detection part 6 (GPS receiver), and information showing a relative position from a relative angle detection part 5 and a vehicle I/F part 10. When the vehicle conveyed in the non-self-traveling state reaches the conveyance destination, a standard used when the vehicle position is estimated based on the detection result by the absolute position detection part 6 (GPS receiver) is mitigated. A plurality of standard tables A, B where different standards are described are prepared, and when the vehicle conveyed in the non-self-traveling state reaches the conveyance destination, a standard table having a milder standard condition is used.
