PROBLEM TO BE SOLVED: To provide a high-performance thermal head which can favorably transmit heat in a substrate to a heat sink, and to provide its manufacturing method and a thermal printer. SOLUTION: In the thermal head, a head substrate 1 with a heating element array 4 is placed on the heat sink 7 with a pair of grooves 7a and 7b so that an immediate down region of the heating element array 4 is located at a gap between the pair of grooves 7a and 7b. Moreover, a resin material 8 and double-faced tapes 9a, 9b are interposed at the immediate down region of the heating element array 4 and at the other region between the head substrate 1 and the heat sink 7, respectively. A plurality of slits 7c along a longitudinal direction of the grooves 7a and 7b are provided at inner wall faces of the pair of grooves arranged at both sides of an upper face of the heat sink located immediately below the heating element array 4.
