There is provided a heating head enabling short heating head units to be connected with heating elements being not so long and also enabling heating head units to be connected so as to be adapted to long and two-dimensional media. On one surface of a rectangular head substrate 1 having long sides and short sides, a strip-like heating element 2 is provided continuously from one end to the other end of the head substrate 1 along the long side of the head substrate. A pair of electrode connecting portions 2a made of the same material as that of the heating element 2 and extending along the short side of the head substrate 1 is provided at both ends of the heating element 2. A pair of electrodes 3 is formed between the heating element 2 and a side edge of the long side of the head substrate 1 at the side where the electrode connecting portions 2a are provided, so that the electrodes are partially overlapping with the pair of electrode connecting portions 2a, respectively, thereby being electrically connected to each other. Also, a substrate temperature control means 4 is provided. |
