Zusammenfassung:	Provided is a metal joint (5) including: a Ag-Cu-Zn layer (7); and Cu-Zn layers (6) joined to both surfaces of the Ag-Cu-Zn layer (7), wherein the Ag-Cu-Zn layer (7) has a composition in which a Cu component is 1 atm % or more and 10 atm % or less, a Zn component is 1 atm % or more and 40 atm % or less, and the balance is a Ag component with respect to the total 100 atm %, and wherein the Cu-Zn layers (6) have a composition in which a Zn component is 10 atm % or more and 40 atm % or less and the balance is a Cu component with respect to the total 100 atm %. It is therefore possible to obtain the metal joint (5), which is capable of joining metal base materials to each other without being limited to aluminum-based materials, and also have high mechanical strength.
