摘要：
Embodiments of the present invention help to provide a sealed hard disk drive (HDD) with high reliability. According to one embodiment, a HDD is a hermetically sealed HDD. A base has an opening of a through-hole on its bottom; a feedthrough is provided so as to close the opening. A flange of the feedthrough has a larger outline than the opening, and its rim is joined to the base with solder at the solder joint. The solder at the solder joint is mainly composed of Sn and contains 15 atomic percent to 27 atomic percent of indium. This solder reaches the γ phase from −150° C. to 120° C. Accordingly, even if the HDD has been exposed at low temperature for a long time, the solder joint is not broken so that helium gas does not leak.
