Abstract
A magnetic head includes a metal plate having a conductive pattern, and a slider having a head element and a connecting terminal electrically connected to the head element, and fixed on the metal plate. The connecting terminal and the conductive pattern are connected by ultrasonically bonding a ball bump thereto. The ball bump has on its surface a projecting portion extending in the direction that links the connecting terminal and the conductive pattern. A bonding capillary for use in the ultrasonic bonding includes a tip section having a through hole for passing a wire therethrough. The tip section also has a recessed portion centered on the through hole, and a groove that reaches the outer surface of the tip section across the center of the recessed portion.
