ABSTRACT

A method for manufacturing a soldered product by soldering a solder object
portion, including: a solder supplying step that causes a cylindrical
soldering iron having a through hole to contact with the solder object portion
to supply a thread solder piece to the solder object portion from the through
hole; a heating step that heats the thread solder piece with the cylindrical
soldering iron and causes to melt the thread solder piece at the solder object
portion; and a curing step that cures a melting object of the thread solder
piece to solder the solder object portion. The thread solder piece is composed
of a core containing a flux and a coating member containing a solder alloy
that covers the core. The flux has a rosin having an acid value which is
substantially as a main component thereof.
