Abstract
To develop the highly sensitive Magneto-Impedance sensor, the amorphous ribbon was micro-processed to meander type sensor pattern, and its external magnetic field dependence of impedance was investigated. The impedance of the pattern had peak value at the magnetic field of 13 Oe and its changing ratio was about 170%. The impedance change per unit magnetic field was about 36% at bias field of 6 Oe, in which the output with high sensitivity and linearity could be obtained. The magnetic field resolution of the sensor module, which consist of the amorphous pattern and driving circuit, was about $10^{-3}$ Oe.
