To provide an electrostatic separator capable of precisely separating plastics by types even if plastic pieces in the form of sheet and film are included.

In the plastics separation equipment that separates plastic pieces by types by throwing the friction electrified plastic pieces into electrostatic field between a drum electrode and an opposed electrode having high voltage applied thereto and altering the falling locus of the plastic pieces, the plastic pieces are agitated in a casing 31 by an agitation device 37 prior to friction electrification of the plastic pieces and are heated from a softening temperature or more to a melting temperature or less by heated air from a heating carriage device 36 and then carried to a discharging port 33 side and further heated by means of an agitation part component 37a by high-frequency induction through a supplementary heating device 39 to heat-shrink the plastic pieces in the form of sheet and film into roll form or bulk form. Thereby, the adhesion of the plastic pieces to each other by static electricity is prevented.
