Description
Technical Field
The patent of the anti-coating backflow device relates to a spraying device, in particular to a part which sprays coating on the surface of an object and prevents the coating from flowing backwards due to the fact that the pressure in a coating container is greater than the external pressure.
Background

In an ink jet recording head as a typical example of a liquid ejecting head, ink from an ink cartridge storing ink is generally supplied to a nozzle opening through an ink supply needle inserted into the ink cartridge and a flow path, and when a piezoelectric element is driven, the ink is ejected from the nozzle opening. The invention provides a method for manufacturing a liquid ejecting head, and a liquid ejecting apparatus, which can prevent a piezoelectric body from cracking due to a longitudinal tensile force applied to the piezoelectric element from a substrate. The flow channel forming substrate is provided with a piezoelectric element having a width in a reference direction longer than a width in a perpendicular direction. The nozzle plate is bonded to the surface of the flow path forming substrate opposite to the piezoelectric element at a temperature lower than the normal temperature. As the nozzle plate, a nozzle plate is used in which the 1 st thermal expansion coefficient in the 1 st direction of the bonding surface to which the flow path forming substrate is bonded is smaller than the 2 nd thermal expansion coefficient in the 2 nd direction, and the 1 st thermal expansion coefficient is smaller than the thermal expansion coefficient of the flow path forming substrate.
