In a connecting material of the present invention, a Zn series alloy layer is formed on an outermost surface of an Al series alloy layer. In particular, in the connecting material, an Al content of the Al series alloy layer is 99 to 100 wt. % or a Zn content of the Zn series alloy layer is 90 to 100 wt. %. By using this connecting material, the formation of an Al oxide film on the surface of the connecting material at the time of the connection can be suppressed, and preferable wetness that cannot be obtained with the Zn—Al alloy can be obtained. Further, a high connection reliability can be achieved when an Al series alloy layer is left after the connection, since the soft Al thereof functions as a stress buffer material.
