<P>PROBLEM TO BE SOLVED: To provide an array-type magnetic sensor substrate that does not require a large system for calibration of dynamic detection sensitivity and is easily calibrated. Ž<P>SOLUTION: This array-type magnetic sensor substrate 10 includes a printed board 1, an array-type magnetic sensor 2 arranged linearly on one surface of the printed board, a pattern line 4 printed and molded on the plane of the printed board, on one side or both sides of right and left string axes of the array-type magnetic sensor, in parallel with the string axes, and at a predetermined interval, and a pulsed current generating circuit 3 for making a predetermined pulsed current flow to the pattern line. A reference magnetic field during calibration is generated by making the pulsed current flow to the pattern line, and the detection sensitivity of the array type magnetic sensor is calibrated.
