To achieve improvements in heat generation efficiency and strength against external load, provided is a thermal head (1), comprising: a supporting substrate (3); a heat accumulating (5) bonded onto a surface of the supporting substrate (3); and a heating resistor (7) provided on the heat storage layer (5), wherein: a concave portion (2) is provided in a region, which is opposed to the heating resistor (7), of at least one of the surface of the supporting substrate (3) and a surface on a side of the supporting substrate (3) of the heat accumulating portion (5); and a center line of a hollow heat insulating layer (4) formed, by the concave portion (2), between the supporting substrate (3) and the heat storage layer (5) is shifted with respect to a center line (X) of the heating resistor (7).
