A cutting jig cuts bonding material of a terminal joint between a magnetic head's slider and a flexure's wiring terminal. A base of the jig receives the slider. A blade moves along the base and faces a front side wall of the slider in a moving direction. An upright portion of the jig is formed on the base and has a stop face that faces a rear side wall of the slider in the moving direction. The blade moves toward the slider to come into contact with the bonding material, and is pressed to the front side wall of the slider. The bonding material is interposed in the moving direction while the rear side wall of the slider is brought into contact with and is stopped by the stop face when the slider is set on the base and the bonding material is cut.
