Abstract
A film forming device includes a cylindrical evaporation source, closing members, and an auxiliary electrode. The cylindrical evaporation source is configured to accommodate a workpiece in an internal space of the cylindrical evaporation source. The cylindrical evaporation source is configured to discharge ions from the cylindrical evaporation source by arc discharge such that the ions are deposited on a surface of the workpiece. The closing members close the internal space. The auxiliary electrode is disposed along an inner wall surface of the cylindrical evaporation source. The auxiliary electrode is configured to be grounded or to be applied with a positive voltage such that electrons of the internal space flow to the auxiliary electrode.
