Zusammenfassung:A member includes a first metallic region made of a first material; a second metallic region made of a second material that is a different from the first material; and a mix region made of mixture of the first and second materials between the first and second metallic region. In a cross-sectional view, an interface between the first metallic region and the mix region is represented by a line having a first curved line protruding toward the first metallic region and a second curved line protruding toward the first metallic region, and an angle at a cross point of the first and second curved lines, the angle being made by a tangent line of the first curved line and a tangent fine of the second curved line in a region of the first metallic region, is equal to or larger than 70 degrees and smaller than 180 degrees.
