<P>PROBLEM TO BE SOLVED: To provide a suction nozzle having resistance to wear of a corner of a suction hole and a function for preventing stress concentrated in the corner and a manufacturing method therefor. <P>SOLUTION: This suction nozzle is constituted in such a way that the suction hole 3 continuous with negative pressure is provided on a suction face 2 at a tip of the nozzle to suck a part on the suction face 2, transfer it to a predetermined position, and mount it at the predetermined position. The suction face 2 is made of a material harder than a material of the part, and a dispersion means 5 for dispersing concentrated stress generated on the suction face 2 when mounting the part is provided to prolong service life of the nozzle 1. <P>COPYRIGHT: (C)2003,JPO |
