Abstract: The purpose is, in mounting a semiconductor device onto a substrate, to make it easy to identify the remaining amount of an auxiliary joining agent, to stabilize the dispensing amount of the auxiliary joining agent, and to prevent a shortage of the auxiliary joining agent. Also for the purpose of efficient maintenance of a mounting machine, provided is an auxiliary joining agent adapted to aid joining of metals and prepared by dissolving a colorant in a solvent having a reducing property of removing an oxide film on a metal surface. The auxiliary joining agent is produced by a method including a step of mixing a solvent having a reducing property of removing an oxide film on a metal surface, and a colorant having a property of dissolving in the solvent.
