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.

Tire wear measuring device and power generating device

A magnetic sensor including a first magneto resistive effect element located on a first surface of a substrate and having a sensitivity axis in a first direction that is one of in-plane directions of the first surface, a positioning soft magnetic body including a first most proximal portion of which a relative position with respect to the magneto resistive effect element is defined, and provided in a non-contact manner with respect to the first magneto resistive effect element, and a first soft magnetic body and a second soft magnetic body juxtaposed in the first direction and extending in a direction away from the first surface, and each of the first soft magnetic body and the second soft magnetic body is magnetically connected to the positioning soft magnetic body.
