Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a magnetic sensing element with a simple constitution and low production cost and proper for constituting by combining in an oscillation type detection circuit. SOLUTION: Two magnetic paths are formed by providing a frame shape core in the middle of a magnetic core. On one magnetic path of the frame shape core, a firs conduction wire is wound and on the other magnetic path, a second conduction wire is wound so that the first and the second conduction wires do not overlap on a plane. It is constituted so that magnetic permeabilities of the two magnetic paths are different and detection sensitivity of external magnetic field by magnetic impedance effect is made high.
