ABSTRACT:
A thermal head of the invention has heating resistors each formed between opposite electrodes of a plurality of pairs of opposite electrodes on an insulating substrate. Each of the heating resistors is formed of a plurality of rectangular parallelepiped resistive elements which are electrically connected in series and supplied with different applied energy per unit surface area at the time of flowing a unit current in the heating resistor. These resistive elements are so arranged as to be the more distant from the resistive element of which the applied energy per unit surface area at the time of flowing a unit current in the heating resistor is the maximum, the less the applied energy per unit surface area at the time of flowing a unit current in the heating resistor.
