An integrated lead suspension includes a solder ball that is placed between a
lead wiring pad provided on a flexure of the suspension, and a bonding pad provided
on a slider of a head gimbal section. The lead wiring pad and bonding pad are soldered
by melting the solder ball. As a result, there is provided a recessed section into
which a solder ball is placed by way of surface raised sections, using gravitational
force, in the vicinity of the center line of the surface of the lead wiring pad.
In this way the position of the solder ball is not displaced from the center line
when a bonding pad and lead wiring pad are connected by means of a solder ball.
