To provide a contact condition estimation device which can furnish an understandable result with a simple structure.SOLUTION: A contact condition estimation device 1 estimates a contact condition between a wheel and a rail during traveling of a vehicle. The contact condition estimation device comprises a wheel measurement unit 2 for measuring a wheel section shape, a rail measurement unit 3 for measuring a rail section shape during vehicle traveling, a position determination unit 4 for measuring a relative physical relationship between the wheel section and the rail section during vehicle traveling and an estimation unit 6 which estimates a contact condition of the wheel and the rail based on the measurement results of the wheel measurement unit, rail measurement unit and position determination unit.SELECTED DRAWING: Figure 1
