Abstract: A tire wear measuring device that detects wear of a tire based on a magnetic field from a magnetic object embedded in the tire includes magnetic sensors and a battery. The battery is capable of transmitting the magnetic field from the magnetic object, and has an outer edge from which the magnetic field from the magnetic object is emitted as an emission magnetic field. Each of the magnetic sensors is disposed in a position where the emission magnetic field is detectable by the sensor.
