MAGNETIC MEASUREMENT ELEMENT GROUP AND MAGNETIC DIRECTION MEASURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve excitation efficiency and detection efficiency of a sensor. SOLUTION: A first conductive line 11 and a second conductive line 12 are wound around magnetic cores 10a and 10b consisting of a soft magnetic material. A plurality of magnetic detection elements 2a and 2b in which a detection coil 14 for detecting an external magnetic field is composed of the first conductive line 11 and in which an excitation coil 13 for exciting the magnetic cores 10a and 10b is composed of the second conductive line 12 are arranged in parallel. The first conductive line 11 and the second conductive line 12 are successively wound around the magnetic cores 10a and 10b of the adjacent magnetic detection elements 2a and 2b.
