Abstract
In a magnetoresistive magnetic head which has a permalloy film as the magnetoresistive film and also has a shunt film for applying a transverse biasing magnetic field, an Nb film having an electrical resistivity of not more than 30 .mu..OMEGA.cm is formed as the shunt film by the electron-beam evaporation method to increase the heat resistance of the magnetoresistive element, thus making it possible to increase the temperature at which the magnetic head is manufactured.
