| 摘要 |
The invention provides a heat generating resistant element having a high durability and a high resistance suitable for constituting an electrothermal converting member in an ink jet head or an ink jet apparatus. There is employed, as the heat generating resistant element, a film constituted of Cr, Si and N, having a composition of Cr: 15 to 20 at. %, Si: 40 to 60 at. % and N: 20 to 45 at. %, which constitute 100 at. % or substantially 100 at. %.
