To provide a soldering iron tip capable of maintaining sufficient bonding strength for a long period of time. To provide a soldering iron tip characterized by comprising a main body having a wire-bonding top surface, said top surface has a tiny concavo-convex shape, in which the tip of top portion of the convex parts of concavo-convex shape is smaller than the tip of top portion of the concave part of concavo-convex shape. In the soldering iron tip, the area of the top portion of the convex part is larger than that of the top portion of the concave part when viewed from the direction perpendicular to the top surface. |
