Abstract
It is an object of the present invention to provide a magnetic sensor which is suitable to be manufactured in a large amount, has a high sensitivity, and is easy to handle. A first outer layer section A is formed by laminating a plurality of magnetic sheets one upon another. A coil section is formed by laminating a plurality of coil-patterned sheets one upon another. A second outer layer section is formed by laminating a plurality of magnetic sheets one upon another. Each of the sheets forming the coil section B has its central portion formed by an elliptical magnetic body and its surrounding portion formed by a non-magnetic body on which a coil pattern is formed by a film located on the non-magnetic body.
