An object of the present invention is to provide a liquid-jet head and a liquid-jet apparatus each capable of stabilizing liquid ejection characteristics in favorable states, and also capable of preventing destruction of a vibration plate. Disclosed is a liquid-jet head including a laminated electrode which is provided on the vibration plate outward of a region corresponding to the piezoelectric elements, and is electrically connected to the lower electrode. In the liquid-jet head, a stress relaxing layer is provided at least in regions corresponding to edge portions of the laminated electrode between the laminated electrode and the vibration plate, the stress relaxing layer being made of a material having a linear expansion coefficient greater than that of the vibration plate and less than that of the laminated electrode.
