Abstract

A hermetic terminal for a hard disk device (HDD device) that has an excellent gas barrier property and can be assembled in a small number of man-hours, and a hard disk device are provided. The hermetic terminal for an HDD device includes a metal eyelet, insulating glass which seals the metal eyelet on a side of an inner diameter of the metal eyelet, and a lead sealed by the insulating glass to pass therethrough. The lead includes a contact made of a conductive elastic material.
