A thermal head comprises a head circuit board (2) having a surface carrying a heating resistor line (4) and at least one drive element (5) for heating the resistor line. The drive element is enclosed in a resinous package (14). At least a surface portion of the resinous package (14) is electrostatically conductive but electrically non-conductive to work as antistat. The antistatic surface portion or entirety of the resinous package (14) may be made of electrically non-conductive matrix resin which contains a predetermined percentage of electrically conductive substance. <IMAGE>
