[Object] To provide a thermal head having improved sealability.

[Solution] A thermal head X1 includes a substrate 7, a heat storage layer 13 disposed on the substrate 7 and including a bulging portion 13a, heating elements 9 disposed on the bulging portion 13a, a protective layer 25 disposed on the heating elements 9, and a covering layer 27 disposed on the protective layer 25. The covering layer 27 includes a first portion 27a disposed apart from the bulging portion 13a, and a second portion 27b disposed between the bulging portion 13a and the first portion 27a. The height of the second portion 27b from the substrate 7 is smaller than the height of the first portion 27a from the substrate 7. Thus, the sealability of the thermal head X1 can be improved.

The thermal print head includes a heat generating resistor, a wiring layer that is connected to the heat generating resistor, and a protective layer that covers the heat generating resistor and the wiring layer. The protective layer is an insulating layer to which diamond particles are added.
