<p>There has been a problem of clogging of a suction hole of a vacuum suction nozzle due to deposition and adhesion of dusts, dirt, and solder debris in the electrostatically charged state on an inner surface of the suction hole. A vacuum suction nozzle, wherein the leading end has a suction surface composed of a ceramic material and provided with a suction hole, is provided to solve such problem. A plurality of protrusions having an electrical resistance smaller than that of the main component of the ceramic material are formed on the inner surface of the suction hole. Thus, when sucking an electronic component (15), even in the case where dusts, dirt and solder debris sucked at the same time from the suction hole are electrostatically charged, static electricity is discharged by being brought into contact with the protrusions (7). Thus, deposition of the dusts, dirt and the solder debris due to adhesion thereof on the inner surface can be suppressed.</p> |
