Abstract

Provided is a detection device (10) that detects a pulse voltage generated by a magnetic sensor such as, for example, a magnetic element (11) capable of causing a large Barkhausen jump. The detection device (10) is characterized in that the device comprises a power supply generation circuit (12) for generating an electric power by making use of a pulse voltage generated by the magnetic sensor and a processing circuit (13) operating by the electric power generated by the power supply generation circuit (12) and executing a predetermined process.
