PROBLEM TO BE SOLVED: To precisely apply the desired quantity of an organic material on the surface of a contact point by ejecting the organic material through plural through-holes having the inside diameter equal to or below a specific value to coat the surface of the contact point with the organic material. SOLUTION: Jetting parts 10 formed by perforating nozzle holes 9 having <=50μm diameter respectively in about 10 lines 2 rows are arranged at 3 places in parallel on the under surface of an ejecting head part 8. The organic material diluted by isoprophyl alcohol or the like, e.g. CRC (a contact point lubricant agent prepared by dissolving a mineral oil, a fatty acid ester, a petroleum sulfonate, a metallic soap or the like in a petroleum based solvent, a halogenated hydrocarbon or the like) or a non-volatile contact point lubricant (e.g. a contact point lubricant prepared by dissolving a non-volatile >=2 polyhydric alcohol in a non-volatile univalent alcohol, ether) is ejected to the surface of the contact point from each nozzle 9. The dropping quantity is controlled to equal to below several nl (10<-10> l) per one time of the jetting.
