PURPOSE:To provide a highly concentrated multi-array recording head by a method wherein a circumferential surface of a nozzle pipe is provided with an electro- thermal transforming means, a common electric pole terminal and a leading electric pole terminal, and a plurality of pipes are multi-arranged on an insulative base plate. CONSTITUTION:Electro-thermal transforming means 102 is directly attached to the nozzle pipe 12, electric poles 72 and 122 for applying electric pulses to the heater for each of the pipes are made on a base plate 62, and electric poles 72 and 122 are closely contacted with the transforming means 102 for each of the nozzle pipes. Conductive coating of a desired pattern is printed on the base plate 62, a metal filmed by evaporation process etc. is etched in its pattern to make an electric pole corresponding to each of the nozzle pipes, heater element of each of the pipes is connected to the electric pole by adhesive agent and thereby a recording head of multi-nozzle array type may easily be made. |
