A thin film magnetic head has a main magnetic pole piece, a magnetoresistance effect element, a bias layer giving a bias magnetic field to the magnetoresistance effect element, an auxiliary magnetic pole piece and an insulating layer leaving a space between the main magnetic pole piece and the auxiliary magnetic pole piece, the main magnetic pole piece is almost disposed in parallel with the magnetoresistance effect element, a distance between the main magnetic pole piece and the magnetoresistance effect element is selected from 1 nm to 1 .mu.m.
