Abstract:
Provided is an Au-based solder alloy that has high bonding reliability even when its Au content is lower than that of a conventional Au-based solder alloy. The Au-based solder alloy is used for sealing or bonding a ceramic electronic component and made of an Au—Sn—Ag alloy containing 21.1 to 43.0% by mass of Sn, 0.1 to 15% by mass of Ag, and a balance of Au and inevitable impurities, an Au—Ge—Sn alloy containing 9.5 to 15% by mass of Ge, 2 to 10% by mass of Sn, and a balance of Au and inevitable impurities, or an Au—Ag—Ge alloy containing 5 to 18% by mass of Ag, 7 to 20% by mass of Ge, and a balance of Au and inevitable impurities. When the Au-based soldering ball is crushed in one direction, a maximum stress before cracking occurs is 2.0×10 2  N/mm 2  or more, and a square root of strain before the cracking occurs is 0.40 or more.

Claim (Index 3):
The Au-based soldering ball according to  claim 1 , comprising 9.5% by mass or more but 15% by mass or less of Ge, 2% by mass or more but 10% by mass or less of Sn, and a balance being Au except for inevitable impurities.
