A wear amount detection device to detect that a tire is in a worn state, during running, without a special sensor. The device includes a rotation sensor detecting rotation of a wheel to measure a speed of an automobile; a signal processing extracting rotation speed fluctuations synchronized with rotation, from a rotation signal detected by the rotation sensor, and obtain a rotation speed fluctuation pattern synchronized with rotation, from rotation speed fluctuations over a plurality of rotations; and a wear state determination configured to obtain, from the obtained pattern, a value of a component induced by a characteristic embodied in a tire of the wheel, the value varying in accordance with a wear state of the tire, to estimate a wear state of the tire, and to output the state.
