ABSTRACT:
The thermal head is comprised of several blocks each containing a plurality of heating elements. Each heating element has a pair of first and second lead electrodes which extend in the same direction from the heating element. The first lead electrodes are connected through corresponding switching elements to a first common electrode within each block. The second lead electrodes are directly connected to a second common electrode disposed adjacently to the first common electrode. The first and second common electrodes have a substantially identical tapered shape, and they are tapered in opposite directions to each other. The second lead electrodes are arranged to connect to one side of the tapered shape of the second common electrode.
