Abstract
A thermal head X1 according to the present disclosure includes a substrate, a heat generator, an electrode, and a protective layer. The heat generator is positioned on the substrate. The electrode is positioned on the substrate and connected to the heat generator. The protective layer covers the heat generator and part of the electrode. The protective layer contains titanium and nitrogen. The protective layer satisfies P2>P1 where P1 is the peak intensity of X-ray diffraction of the (111) plane, and P2 is the peak intensity of X-ray diffraction of the (200) plane.
