RECORDING HEAD AND RECORDING APPARATUS PROVIDED WITH SAID RECORDING HEAD

摘要

Provided are a recording head which can satisfactorily maintain the function as a protective layer and a recording apparatus provided with said recording head. A thermal head (10) has a substrate (20), a heat generating element (40a) positioned on the substrate (20), and a protective layer (60) provided on the heat generating element (40a). The protective layer (60) includes a first layer (62) and a second layer (63). A plurality of layers of the first layer (62) and the second layer (63) are alternately deposited. The materials forming the second layer (63) have a higher resistance to sublimation compared to the materials forming the first layer (62).
