The present invention discloses a method and apparatus for coating adhesive for mounting parts onto a printed substrate in which an adhesive coating nozzle is arranged in correspondence to the printed substrate placed on an X-Y table controlled to be moved in an X-Y direction, and said coating nozzle is operated to coat the adhesive within an adhesive storage tank in position on each of the printed substrates, at which a waste coating is carried out for said coating nozzle before the latter perform the coating operation with respect to the printed substrate, whereby even if the adhesive trickles from the end of the nozzle to bring forth the liquid-drip state, the adhesive in the liquid-drip state is eliminated by the waste coating of the coating nozzle to prevent the adhesive in the amount more than as needed from being coated on the printed substrate, thus always maintaining a stable amount of coating thereby positively preventing occurrence of irregularities in quantity.
