PROBLEM TO BE SOLVED: To provide a flux applicator in a conductive ball mounter where the worker does not need to find out the origin of flux. SOLUTION: A mask 10 is made of conductive material, and it is connected to the earth. Moreover, a storage 11 for flux 6 is made of conductive material, and it is connected to an oscillating circuit 13, in condition that it is insulated electrically from the earth. Moreover, the frequency Fh of the oscillating circuit 13 at the time of having soaked the bottom end of a solder ball 3 by (h) from the surface is obtained in advance. Then, when applying flux, the frequency F of the oscillating circuit 13 is monitored while lowering the mask 10, and when the frequency F comes to Fh, the mask 10 is elevated.
