Abstract
The invention relates to a thermal head which comprises: a plurality of heating elements arranged at regular intervals on the top surface of an electrically insulating substrate; a common electrode connected to one ends of the respective heating elements; a plurality of discrete lead wires connected to the other ends of the respective heating elements and led out in directions at predetermined angles with respect to the direction of arrangement of the heating elements; and driving IC including a plurality of connecting pads arranged nearly parallel with the direction of arrangement of the heating elements and with intervals smaller than the intervals of arrangement of the heating elements, the connecting pads connected to lead-out sections of the discrete lead wires, wherein the connecting pads of the driving IC are arranged with intervals between the neighboring connecting pads which vary depending on the sine values of angles between the direction of arrangement of the heating elements and the lead-out directions of the respective discrete lead wires.
