A brazing material which can be melted at a suitable temperature at which damage is not given to a device inside a package upon sealing, and besides the brazing material is not remelted, e.g., upon mounting to a board, and which has a low temperature difference between a liquid and a solid. The brazing material is made of a Au—Ga—In ternary alloy, wherein weight concentrations of the elements lie within a region of a polygon with a point A (Au: 90%. Ga: 10%, In: 0%), a point B (Au: 70%, Ga: 30%, In: 0%), a point C (Au: 60%. Ga: 0%. In: 40%) and a point D (Au: 80%, Ga: 0%. In: 20%) as vertexes. excluding lines on which In and Ga become 0%, in a Au—Ga—In ternary phase diagram.
