A decelerating factor estimating device (1) configured to estimate a decelerating factor of a vehicle (2) includes a drive force acquiring unit (62) configured to acquire a drive force of the vehicle (2); a vehicle speed acquiring unit (60) configured to acquire a vehicle speed of the vehicle (2); an acceleration acquiring unit (61) configured to acquire an acceleration of the vehicle (2); and a decelerating factor estimating unit (63, 64, 65, 68) configured to estimate a plurality of decelerating factors based on a relationship of the acquired drive force, speed, and acceleration, wherein the decelerating factor estimating unit (63, 64, 65, 68) determines a type of the decelerating factor to estimate based on a traveling state of the vehicle, and at the time an estimated value of a first decelerating factor is converging, further widens a range of the traveling state of the vehicle to execute an estimation process of a second decelerating factor than a case where the estimated value of the first decelerating factor is not converging.
