。 One end of the core material made of a magnetic material is opposed to the tooth tip of a gear that rotates in conjunction with the wheel, a permanent magnet is placed on the other end of the core material, and a coil is wound around a predetermined part of the core material. In a wheel speed sensor that detects the rotational speed of a wheel based on the electromotive force generated in the coil as the gear rotates, a yoke made of a plastic magnet with high magnetic permeability is connected to the permanent magnet. A wheel speed sensor featuring:
