In a thermal head consisting of one or more substrates, each of the substrates comprises a heating element, common electrodes arranged on one of the sides of the heating element, and individual electrodes arranged on the other side of the heating element. In the vicinity of the side edges of the substrate, the patterns of the two types of electrodes extend from the heating element toward the upper edge and lower edge of the substrate corresponding to the top side and bottom side of the trapezoid, respectively, in such a manner as to be directed at an angle toward the central portion of the substrate. This enables a plurality of substrates to be manufactured with the same electrode patterns, and all the substrates to have the same data transfer direction to simplify the wiring.
