A chip junction nozzle in that opposite slant planes which come into contact with edges of 2 sides of the chip in parallel centering around a nozzle center, and a vacuum suction hole opened in the nozzle center are provided, and the slant plane is formed into a mirror surface having the surface hardness more than HrC40. Further, when the surface roughness of the mirror surface is expressed by the average roughness of the center line, the average roughness of the center line is not more than 1.6 &mgr;m.
