<P>PROBLEM TO BE SOLVED: To provide a magnetometric sensor capable of forming, especially a connection part in a small shape, and controlling deviation of a middle-point potential. Ž<P>SOLUTION: In this magnetometric sensor, a plurality of chips equipped respectively with a magnetoresistance effect element whose electric characteristic is changed with respect to a magnetic field change are loaded on a substrate, and the magnetic field change is detected based on a change of the electric characteristic. The sensor has on each chip 22, 23, the first connection pad 25 and the second connection pad 26 connected to both ends of the magnetoresistance effect element 24, a wiring layer 32 connected to the first connection pad 25 and formed elongatively, and the third connection pad 33 connected to the end of the wiring layer 32. Each connection pad of each chip 22, 23 is connected electrically together, and an electric circuit including the magnetoresistance effect element 24 and a wiring resistance of the wiring layer 32 is constituted.
