。Prior Art Elements of this type have conventionally had structures as shown in FIGS. 4 and 5. In the figure, 1 is an insulating substrate made of a material such as glass or silicon, 2 is a magnetic field detection resistor pattern made of a material such as nickel iron, and 3 is an electrode. By appropriately arranging the magnetic field detection patterns, the magnetic fields applied to the two patterns are changed, resulting in different resistance changes, and the difference is read as a voltage change.
