The external magnetic field dependency of the impedance, resistance, and inductance of the meander pattern fabricated by using Co-base amorphous ribbon has been investigated in the frequency range of 300 ㎑∼1 ㎓. The amorphous ribbon was patterned to the meander pattern through conventional photolithography and wet etching process. The extremely high sensitivity in impedance changing ratio by external magnetic field was observed. This is due to the transverse magnetic anisotropy the pattern which was induced by magnetic field annealing. The impedance had peak value at the external field of -13 Oe and the impedance changing ratio 100 ${\times}$ (Z$\_$13/-Z$\_$0/)/Z$\_$0/) was about 210％ at the frequency of 50 MHz.
