摘要：: A multistylus head device which comprises a vast plurality of insulated wires embedded in an insulating substrate having through-holes. The present multistylus device is characterized in that the insulated wires have their respective free terminals exposed on one edge of said insulating substrate and disposed in parallel at predetermined equal intervals in close proximity to each other to form electrodes and have their other terminals exposed respectively on the inner walls of said through-holes; and said other exposed terminals of the insulated wires are connected respectively to metal layers electrolessly deposited on the inner walls of the through-holes. The present multistylus head device is compact in size and excellent in reliability of terminal connection and is capable of recording a transmitted information with high density of printing. The exposed disposition of the wires at their respective free terminals in a parallel state at predetermined equal intervals are skillfully realized according to the method of the present invention. Thus, the present device can be produced at low cost, with reliability of the function of the produced device and is suitable for mass-production.
