ABSTRACT:
A nozzle rod (1) is formed by fixing a thick diamond chip (2) to a tip of a nozzle pipe (4) made of a super hard metal, the other end of the nozzle pipe (4) is thinned and the nozzle rod (1) is joined with a shank (5) by way of this end, a tip of the nozzle rod (1) and vicinities thereof are so shaped as to have a predetermined sectional shape, a center hole is formed in the diamond chip (2) by wire electrospark machining and expanded for forming a nozzle slot (10) having a nozzle opening (11) consisting of a center slit (12) and "U-shaped" slits (13, 14) which are disposed symmetrically on both sides of a longitudinal direction of the center slit (12), thereby composing an electronic part adsorbing nozzle (7). This construction enables it to provide an electronic part adsorbing nozzle (7) which is economical and excellent in durability.
