Abstract:
A magnetic sensor, comprising:a coil section formed by laminating a plurality of non-magnetic sheets, each of the non-magnetic sheets having a respective coil pattern and a respective magnetic body section disposed inside the respective coil pattern before the non-magnetic sheets are laminated together, the coil patterns being coupled together to form a coil, the magnetic body sections being coupled together to form a central magnetic body located within the coil; first and second outer layer sections, each of said outer layer sections being a lamination of a plurality of magnetic sheets, the first and second outer layer sections being laminated to the top and bottom of the coil section, respectively, so that they are coupled to opposite ends of the central magnetic body; and a plurality of electrodes electrically connected with first and second end portions of the coil, respectively.
