Abstract
An electrostatic write head includes of an insulating plate provided with conductor tracks which comprise end portions which are situated in a strip-shaped region which extends across the central portion of the plate, perpendicularly to the longitudinal direction of this region. The end portions comprise thickened parts which serve as write electrodes. Successive adjacent end portions are connected to conductor tracks which extend in opposite directions. An insulating layer covers the end portions, but leaves the thickened parts bare.
