ABSTRACT:
The present invention is directed to an electrostatic recording head comprising an electrode substrate made of an insulating material, a plurality of parallel recording electrodes made of a conductive material and formed on at least one of the side surfaces of the electrode substrate so that tip portions of the recording electrodes are in alignment, a rigid outer member made of an insulating material for covering both side surfaces of the electrode substrate to fix the electrode substrate, and an insulating resin layer filled into a space formed at least at a part of the tip portions of the recording electrodes between each of the side surfaces of the electrode substrate and the outer member, the insulating resin layer also filling gaps between every adjacent two of the recording electrodes, whereby substantially preventing electromigration.
