An electrostatic deflector that can be manufactured easily and very accurately without using a member for positioning is provided. After multiple slitstohave been formed in the same direction as that of the bus bar of an approximately conical electrode materialwhose large-diameter section is formed with flange portionstofor installation on an insulator, each of the flange portions is coupled with the insulator, then the electrode materialis cut along extension lines of the slitsto, and thus, multiple electrode members electrically isolated from one another are formed.
