Sensor for detecting variation in magnetic field.

摘要

A sensor for detecting variation in magnetic field comprises a sensor element part having a terminal for detecting variation in magnetic field and generating a signal, an output wire (107) having an end connected to the terminal for outputting the signal from the sensor element part to the exterior, a case (112) having an opening on a side being close to the output wire (107) for containing the sensor element, a first resin part (109a) filled in the case for covering the sensor element part and a second resin part (109b) formed to seal the case filled up with the first resin part (109a) on an opening side.
