Beschreibung
Zusammenfassung:	A thermal head (10) comprises a plurality of parallelogrammatic resistors (14) for generating heat formed on an insulated substrate (12) made of, for example, ceramics or alumina. The resistors (14) are aligned at regular intervals, and one pair of opposite sides of each resistor (14) are connected individually to lead electrodes (16, 18). A ratio of a length (Lb) of the one opposite sides to that (La) of the other opposite sides is not greater than 1.5, and an acute angle formed by two adjacent sides of the resistor, is not greater than 45. The resistor is heated by various electric currents to record printing dots of various sizes.
