Thermal head for thermal recording |
摘要 |
Disclosed is a thermal head comprising a protecting film composed of tantalum silicon oxynitride. An undercoat film may be formed between this protecting film and heat-generating resistors and electrodes. This protecting film is excellent in the abrasion resistance and oxygen barrier property and acts as an excellent barrier to alkali metal ions to be injected into the head from a heat-sensitive recording paper.
