Abstract
To efficiently manufacture a feedthrough used in a disk drive device having a hermetically sealed enclosure, embodiments of the present invention manufacture a feedthrough used in an HDD having a hermetically sealed enclosure. An embodiment of a manufacturing method of the present embodiment manufactures a columnar body, cuts the columnar body in the direction vertical to the axes of pins, and cuts out a feedthrough. Then, necessary plating is made on the outer surfaces of the cut out feedthrough. The columnar body comprises a hollow tube, a plurality of pins inserted inside the tube, and an insulating sealant filled inside the tube. This manufacturing method achieves efficient manufacture of the feedthrough.
