Abstract:
The present invention suppresses fracture at an interface between different materials, and provides a solder joining which includes: a solder joining layer  10  having a melted solder material, containing Sb at more than 5.0% by mass and 10.0% by mass or less, Ag at 2.0 to 4.0% by mass, Ni at more than 0 and 1.0% by mass or less, and a balance made up of Sn and inevitable impurities; and joining members  11  and  123  at least one of which is a Cu or Cu-alloy member  123 , in which the solder joining layer includes a first structure  1  containing (Cu, Ni) 6 (Sn, Sb) 5  and a second structure  2  containing (Ni, Cu) 3 (Sn, Sb) X  (in the formula, X is 1, 2, or 4) at an interface with the Cu or Cu-alloy member  123 , and an electronic device and a semiconductor device including the solder joining.

Claim (Index 20):
An electronic device comprising the solder joining according to  claim 3 .
