PURPOSE:To prevent a polishing flaw from occurring as well as to make uniform finishing attainable, by installing a charge preventive abrasive layer in at least one side of a film-form abrasive tape base material. CONSTITUTION:An abrasive layer 2 may be made up of a binder resin layer inclusive of an abradant subjected to antistatic treatment or another binder resin layer inclusive of an antistatic agent and the abradant-either will do. A binder component is polyester resin or salt, vinegar vinyl resin, or mixed rein of them. Abradant grains to be used for the abrasive layer use a primary grain of 0.1-20mum in grain size of silicon carbide and diamond or the like. The antistatic agent is an amphoteric antistatic agent or the like of a quaternary ammonium salt compound or the like. To manufacture an abrasive tape, the abradant, the binder resin and the antistatic agent are added into such an organic solvent as dissolving the binder resin and the antistatic agent, and they are sufficiently decomposed and dispersed, adjusting a coat agent, and this agent is applied to at least one side of a base material film and dried up.
