Zusammenfassung:To provide a thermal head whose auxiliary heat generation parts can be preferably utilized.SOLUTION: A thermal head 1 has a plurality of main heat generation parts 21a and auxiliary heat generation parts 21b. The plurality of main heat generation parts 21a are arranged in a D1-axis direction along a foundation layer 19, on the foundation layer 19. The auxiliary heat generation parts 21b are positioned on the foundation layer 19, where a direction, in which end parts at both sides in the D4-axis direction orthogonal to the D1-axis direction when viewed in a normal line direction of the foundation layer 19 are joined to each other, inclines with respect to the D4-axis direction.SELECTED DRAWING: Figure 4 【課題】補助発熱部を好適に利用できるサーマルヘッドを提供する。【解決手段】サーマルヘッド1は、複数の主発熱部21aと、補助発熱部21bとを有している。複数の主発熱部21aは、下地層19上において当該下地層19に沿うD1軸方向に配列されている。補助発熱部21bは、下地層19上に位置しており、下地層19の法線方向に見てD1軸方向に直交するD4軸方向両側の端部を結ぶ方向がD4軸方向に対して傾斜している。【選択図】図4
