Abstract
In a printer according to the present invention, a diaphragm provided with a thermoplastic layer and a pattern layer is set on the main surface of a pressure chamber forming part in which a liquid supply passage is formed, when the thermoplastic layer of the diaphragm is pressed, heated and bonded onto the pressure chamber forming part, pressure is applied only to the pattern layer of the diaphragm, no unnecessary pressure is applied to a part opposite to the liquid supply passage in which the pattern layer is not formed, the liquid supply passage is prevented from being blocked by the thermoplastic layer, and operation for bonding the diaphragm to the pressure chamber forming part in which the pressure chamber is formed is facilitated. Further, in the printer according to the present invention, an adhesive layer consisting of thermoplastic resin is formed between the pressure chamber forming part and the diaphragm and the bonding strength of the diaphragm to the pressure chamber forming part is sufficiently secured. Also, in the printer, each nozzle is formed in a nozzle forming member, if an adhesive layer consisting of thermosetting resin is formed between the pressure chamber f…
