Title:
液滴吐出装置及び液滴吐出装置の製造方法
Document Type and Number:
Japanese Patent JP4238285
Kind Code:
B2
Abstract:
A droplet discharging apparatus has a pressure chamber communicating with a nozzle, a vibration film forming a part of the pressure chamber, a piezoelectric element for vibrating the vibration film, a projection joined to the piezoelectric element and transmitting vibration of the piezoelectric element to the vibration film, and a flow path communicating with the pressure chamber. The apparatus has first and second members, with the vibration film, the projection, a groove, and a supply hole communicating with the groove being provided at the first member. The nozzle and the pressure chamber are formed in the second member. The first member and the second member are bonded together to form the flow path in the groove and also the pressure chamber in the recess. The groove and the recess partially overlap to form the flow path and the pressure chamber. A method is disclosed for manufacturing the droplet discharging apparatus.
