Abstract
A first conductor having an Au layer formed on the surface is connected with a second conductor at least the surface of which has conductivity through a solder containing Zn. The first conductor is, for example, a terminal pad () constituting a part of a wiring pattern on a circuit board (), and the second conductor is, for example, a terminal () or a terminal board () of an electronic component (). The first conductor is connected with the second conductor through an Au—Zn alloy layer formed through diffusion of Zn from the solder containing Zn into the Au layer of the first conductor.
