A carriage assembly of a hard disk drive, and a manufacturing apparatus for the same are not susceptible to problems such as flying leads breaking and resin residue being deposited on bonding terminals when the flying leads of a long tail suspension circuit board are pulled off the bonding terminals of a flexible printed circuit board. The flying leads of the long tail suspension circuit board and the bonding terminals of the flexible printed circuit board are ultrasonically bonded together by placing an ultrasonic tool in contact with opposite surfaces of the flying leads to the surfaces that are bonded to the bonding terminals and applying ultrasonic vibration from the ultrasonic tool in a state where the flying leads are pressed onto the bonding terminals. Coating layers composed of a thermally meltable metal that melts at a lower temperature than the material forming the bonding surfaces are respectively formed on the opposite surfaces of the flying leads.
