Such a thermal head has an elongated electrically resistive film on the surface of an elongated base, which is covered with a glass protective film, and a large number of terminals arranged in a comb-like shape on both widthwise edges of this electrically resistive film. They are closely spaced, and a heating current is passed between the pair of terminals for a short time to generate heat locally, so that the part of the thermal paper that comes into contact with the heated area becomes sensitive to heat and forms a dot. It has become. By passing a computer-controlled heating current between all pairs of terminal portions, the individual dots formed on the thermal paper are combined to form a pattern.
