A thin film magnetic head has an air bearing surface and comprises magnetic shield layers, an MR element, bias-applying layers, and a hard magnetic layer. Each of the magnetic shield layers has an end face forming the air bearing surface, and an end face located opposite to the end face. The MR element is located between the magnetic shield layers and on the end face side. The bias-applying layers are located between the magnetic shield layers and are arranged to apply a bias magnetic field to the MR element. The hard magnetic layer is located between the magnetic shield layers and on the end face side. A height of the hard magnetic layer is larger than 1/3 and smaller than 1/2 of a height of each magnetic shield layer.
