PROBLEM TO BE SOLVED: To prevent erroneous charge of a solder since it is difficult to correctly identify the composition and the composition ratio of the solder to be fed into a solder tank. SOLUTION: A solder 8 having the first solder composition suitable for charging in a solder tank 1 and another solder 9 having the second solder composition different from the first solder composition and unsuitable for charging in the solder tank 1 are classified by using a bar-like solder so that the first and second sectional shapes of the solder 8 and another solder 9 in the surface orthogonal to their longitudinal direction are different (circular, rectangular) from each other corresponding to the first and second solder compositions. A solder feeder 10 has a solder pass limiting mechanism 6 having an opening part 7 of the opening shape corresponding to the sectional shape of the solder, and the opening part 7 is formed in such a shape that only the solder 8 to be fed to the solder tank 1 can be passed.
