Abstract

PURPOSE:To ensure easy formation of a conductor wiring pattern and easy connection of a thermal head substrate to an external system even where the density of heat generating elements is high, by disposing an integrated circuit so that control signal terminals are positioned nearer to the heat generating elements than driving output terminals, and providing a part of a conductor pattern beneath the integrated circuit in an overlapping relation with the circuit. CONSTITUTION:In a thermal head, an integrated circuit 1 is so disposed that, for example, 64 bonding wires 4 for connection between 64 heat generating elements 2 and 64 driving output terminals D1-D64 are provided in a spacing l, and control signal terminals (BEO1, 2, LATCH1, 2, CLK1, 2, SI, SO) are located nearer to the heat generating elements 1 that the terminals D1-D64. Further, a part of the pattern of the wires 4 is provided beneath the integrated circuit 1 in an overlapping relation with the circuit 1. Since n (=64) conductor wirings 3 can be set in the range from the width of the circuit 1 of 2mm to about 2.5mm, the wiring pattern can be easily formed. The control signal terminals can thus be connected by cascade connection.
