A reel to reel vacuum sputtering device which suppresses thermal deformation of an insulative material film, forms a metal film at high speed, and enables the productivity improvement and enhancement of neutralization effect on the film. A reel to reel vacuum sputtering apparatus comprises an electron beam irradiator (21) disposed between a feed roller (13) and an evaporating source (16) and emitting charged particles toward a material film (12), an assisting roller (18) disposed between a cooling can roller (14) and a take-up roller (15), in contact with a film forming surface of the materal film (12) so as to guide the travel of the material film (12), a DC bias power source (22) for applying a DC voltage between the can roller (14) and the assisting roller (18), and a neutralizing unit (23) disposed between the can roller (14) and the take-up roller (15) and neutralizing the material film (12). The neutralizing unit (23) is constituted by a two-electrode DC discharge plasma generating source one electrode of which is grounded.
