    摘要： Provided are an actuator device, a liquid jet head and a liquid jet apparatus, which can improve reliability by preventing peeling-off of respective films forming a vibration plate. The vibration plate has a first oxide film (elastic film 50) formed on the one surface of a passage-forming substrate 10, and a second oxide film (insulation film 55) formed on the first oxide film 50 by use of a sputtering method. In only a part of an interface between the first and second oxide films 50 and 55, an altered layer is formed which has a first element that is a constituent element other than oxygen included in the first oxide film 50 and a second element that is a constituent element other than oxygen included in the second oxide film 55, and which is a layer in which a proportion of the first element is lower than that in the first oxide film 50 and a proportion of the second element is lower than that in the second oxide film 55. A proportion of the altered layer in the entire interface between the first and second oxide films 50 and 55 is not more than 10%.
