Abstract
An inkjet head is disclosed which has an ink ejection unit disposed on a silicon substrate and a plate including an ink ejection nozzle disposed corresponding to the ink ejection unit. The plate is formed of a film having a linear expansion coefficient from 50% to 200% of a linear expansion coefficient of the silicon substrate. The film is, for example, composed of aramid. The plate is bonded to a partition layer, by which an ink path linking with the ink ejection nozzle is formed, using an ultraviolet curing adhesive.
