In a hard disk drive, the leading end portion of a main FPC is fixed to the bearing assembly of a carriage assembly. A plurality of connection pads are formed on the leading end portion in sets corresponding to the number of magnetic heads. The connection pads of each set are arranged in a straight line at predetermined intervals. The connecting end portion of a head FPC fixed to the surfaces of each arm and each suspension of the carriage assembly has a plurality of second electrodes pads. These second electrode pads have the same arrangement as that of the connection pads of a corresponding set. The second electrode pads are stacked and soldered on the connection pads of the corresponding sets.
