る電流センサ。 A magnetic sensing element is arranged in the air gap of a magnetic core with an air gap provided in a part of the annular magnetic path, and a current flowing through a coil in which a winding is wound around the magnetic core is detected by the output voltage of the magnetic sensing element. In a sensor, a magnetic core is arranged in a magnetic core that forms an annular magnetic path.
2 air gaps are formed along the magnetic path of the magnetic core.
A current sensor characterized by combining divided coil bobbins and winding a winding wire around the coil bobbin to form a coil.
