A magnetic head assembly equipped with a slider having a magnetic head and a gimbal spring on which the slider is mounted with an adhesive. The gimbal spring is supported by beam portions of a load beam. A thin-film wiring pattern formed on the load beam extends to a surface of the gimbal spring. A tip of the wiring pattern acts as a terminal portion that is connected to input/output terminals integrally formed on the slider. The slider is locked on the gimbal spring by electrically conducting bonding and an adhesive. A plurality of dummy patterns having the same height as the wiring pattern are provided at a position corresponding to where the adhesive is dropped on the surface of the gimbal spring. The adhesive is placed in an area sandwiched by the dummy patterns on the gimbal spring.
