    摘要： A method of forming a piezoelectric layer includes: a drying step for forming at least one ferroelectric precursor film on a lower electrode of a substrate and drying the ferroelectric precursor film; a degreasing step for carrying the substrate into a region facing a hot plate heated to a certain temperature and for degreasing the ferroelectric precursor film in a state where the substrate is supported by a proximity pin; and a baking step for further baking the degreased ferroelectric precursor film to form the degreased ferroelectric precursor film into a ferroelectric film. The piezoelectric layer is formed by repeating the drying, degreasing, and baking steps for the ferroelectric precursor film in a predetermined number of cycles. The degreasing step includes a step of adjusting a heating temperature of the ferroelectric precursor film by adjusting a distance between the hot plate and the substrate and by lowering a temperature of space on an opposite side of the substrate from the hot plate.

    摘要： A liquid ejecting head includes a flow path forming substrate in which pressure generation chambers are formed. The pressure generation chambers communicate with nozzles that eject liquid droplets. Piezoelectric elements are positioned on the flow path forming substrate to generate pressure changes in the pressure generation chambers.
