<P>PROBLEM TO BE SOLVED: To provide a magnetic detecting device, which can have a wider detecting range for an external magnetic field than that of the prior art and which can make a dipole detection highly precisely. Ž<P>SOLUTION: A first magneto-resistance effect element and a second magneto-resistance effect element are formed to have a hard bias layer so that a fixed magnetic layer and a free magnetic layer are made orthogonal in their magnetizing direction thereby to establish a relation between an external magnetic field H and an output value (or a differential potential), as shown in Fig.1. The range for detecting the external magnetic field H can be set wider than that of the prior art. Moreover, there arises no hysteresis, and the output value is straight but not blunt even for the zero external magnetic field, so that the external magnetic field H can be detected highly precisely all over the detecting range.
