    摘要： A crossover construction is disclosed for a thermal-head of a thermal printer. The thermal-head comprises: a substrate insulated material (25, 26); a plurality of heat elements (R) disposed side by side in one row on the substrate; a plurality of lower thin film conductor patterns (29) each of which connects to one of the heat elements (through 28) and extends in direction X; an insulating layer (30) disposed over the lower conductors; a plurality of upper conductor patterns (31, 31') disposed in parallel in another direction Y on the insulating layer so as to form a crossover on the substrate for connecting selected heat elements to common power lines, the upper and lower conductors being selectively connected together through openings in the insulating layer; the crossover construction characterized in that the insulating layer and the upper conductors comprise printed and cured pastes of insulating material and conductive material, respectively, each paste being of the low temperature curing type which can be cured at a temperature low enough not to affect the resistance of the thin film lower conductors (24), and that a metallic layer of low resistance (32) is coated on each of the upper conductors (31, 31') to improve its conductivity.
