<p>A magneto-resistance effect magnetic head having a uniform bias distribution and improved linearity and bias efficiency and adapted for avoiding shorting between a magneto-resistance device and a bias conductor. A magneto-resistance device 5 and a bias conductor 6 for applying a bias magnetic field to the magneto-resistance device 5 are interposed between a lower shielding magnetic member 1 and an upper shielding magnetic member 2. The bias conductor is embedded in a groove formed in the shielding magnetic member provided on the opposite side of forward and rear electrodes with respect to the magneto-resistance effect device. <MATH></p>
