PROBLEM TO BE SOLVED: To obtain a thermal head in which finer patterning is dealt with high pattern accuracy at the time of forming a common electrode and high efficiency print heating can be ensured while eliminating uneven print density even when a low voltage driving printer is used for printing by lowering the wiring resistance between layers. SOLUTION: A lower layer reinforcing electrode is formed to have a tapered circumferential fringe part and an upper layer common electrode is formed to cover the reinforcing electrode.
