PURPOSE:To sharply reduce the number of assembling processes and to obtain an electrostatic multineedle recording head having a high abrasion resistance and durability by a construction wherein a group of recording electrodes in a large number which are constructed by forming a large number of slits in a conductive thin film are formed integrally on one side of a ceramic substrate, and a plurality of control electrodes are formed integrally on the other side of the ceramic substrate. CONSTITUTION:An electrostatic multineedle recording head 1 has a construction wherein a large number of recording electrodes 3 are formed on the opposite sides of a pair of ceramic substrates 2 disposed opposite to each other and the groups of the recording electrodes 3 on the two ceramic substrates 2 are so disposed as to form a zigzag. On each of the ceramic substrates 2, control electrodes 5 are formed on a recording surface whereon the end faces of the recording electrodes 3 are positioned and on a part of the side adjacent to the recording surface, and the recording electrodes 3 and the control electrodes 5 are insulated from each other by thin layers of the ceramic substrates 2 themselves interposed therebetween. The recording electrodes 3 form slits in a conductive thin film formed by coating on the side of each ceramic substrate 2, low-melting glass 6 is filled up in these slits, and thereby the two ceramic substrates 2 and a separator 4 are joined integrally. |
