Claim 0:
1. A brazing material application method comprising:
a supply step of supplying a liquid brazing material containing a fluoride-based flux to a liquid chamber of a discharge apparatus that is configured to have the liquid chamber having a discharge channel, a plunger disposed in the liquid chamber movably forward and backward, and a drive device for moving the plunger forward and backward and to satisfy the formula 1; and
an application step of discharging the brazing material in the liquid chamber from the discharge channel by moving the plunger toward the discharge channel of the liquid chamber by the drive device such that droplets of the brazing material are discharged from the discharge channel, and applying the droplets of the brazing material to a metal member, wherein

[inner diameter (mm) of discharge channel]2×1000/(average particle diameter (μm) of fluoride-based flux)>0.85  Formula 1, and

wherein the inner diameter of the discharge channel, a travel distance of the plunger in forward and backward movement directions, and the average particle diameter of the fluoride-based flux satisfy the following formula 2:

[inner diameter (mm) of discharge channel]2×(travel distance (mm) of plunger in forward and backward movement directions)×(average particle diameter (μm) of fluoride-based flux)×1000<120  Formula 2.
