To provide a highly reliable metallized film capacitor by providing a wire rod for vapor deposition that can suppress the generation of splash upon vapor deposition.
The wire rod 1 for vapor deposition includes a core material 2 that consists of an alloy of magnesium and aluminum, and an oxidized layer 3 that coats an outer peripheral surface of the core material 2, and consists of oxides of at least the magnesium and the aluminum, wherein the thickness of the oxidized layer 3 is 0.3 μm or less. As a result, the splash that occurs because the oxidized layer 3 does not melt but only the core material 2 evaporates in vapor deposition can be suppressed. The dielectric film of the metallized film capacitor formed using the core material 1 for vapor deposition receives no damage by the splash, thereby being highly reliable.
