Abstract
A thermal head comprises a plurality of parallelogrammatic resistors for generating heat formed on an insulated substrate made of, such as ceramics or alumina. The resistors are aligned at regular intervals, and one pair of opposite sides of each resistor are connected individually to lead electrodes. These opposite sides are equal to or longer than the other opposite sides, and an acute angle formed between each two intersecting sides is 45.degree. or less. The resistor is heated by various electric currents to record printing dots of various sizes.
