PURPOSE:To provide the above electrostatic recording head capable of enhancing the mechanical strength of the conductors formed on a wiring board in high density. CONSTITUTION:Conductors 12 are formed on a wiring board 10 by usual photolithographic technique. As the conductors 12, a copper foil is used and the thickness of each of the conductors is set to 5mum. The part having length of 5mm from each of the leading ends of the conductors 2 is used as a recording electrode 120. The width of the recording electrode 120 is set to 50mum and the width of the conductor 12 excepting the recording electrode 120 is set to about 60mum. |
