Abstract

PURPOSE:To make the printing head inexpensive without lowering the function thereof by connecting two circuit substrates by flexible wiring boards to form a matrix wiring. CONSTITUTION:Heating resistors 3 of mXn units are arranged on the surface of the first circuit substrate 2 and one end of each heating resistor 3 is connected to a diode array 4 on the substrate 2. The second circuit substrate 7 is a substrate of matrix wiring and the number of lead wires 8 is equal to n which is the number of the heating resistors per block. The flexible wiring board 9 is made to accord with the pitch of separate terminal electrodes 6 of the first circuit board 2 at the window 101 of the top terminals of concentric U-shaped lead wires 11 of n pieces, while at the window 102 thereof it is made to accord with the pitch of the lead wires 8 of the second circuit board 7. Then, m/2 units of these flexible wiring boards 9 are prepared and laid on the first and second circuit substrates 2 and 7 which are arranged on a base board 1 and bonded thereto. The lead wires of the window 102 and the lead wires 8 of the circuit substrate 7 are connected with each other, whrereby the printing head of an equivalent circuit is formed.
