Abstract
A hermetically sealed magnetic sensor for detecting variations in a magnetic field has a sensor element with an output terminal for detecting variations in the magnetic field and generating a signal. An output wire is connected with one end to the terminal for outputting a respective signal from the sensor element. A case having an opening on a side close to the output wire contains the sensor element. A first thermosetting resin fills the case for covering the sensor element. A second thermoplastic resin hermetically seals the opening in the case.
