Ink jet head for high speed printing and method for it's fabrication

摘要: The invention provides an ink jet head which exhibits a good response characteristic through heating and fast cooling enough to implement high-speed printing. A nozzle plate (10) having orifice (11), substrate (7) constitute part of peripheral wall chamber (31). pressure generating member (20) is provided in the has buckling (1), heater layer (3), diaphragm (5). (1) formed into generally shape its portion attached (7). can be switched between no-displacement state it undergoes substantially no thermal stress, buckled thermally expanded buckled. (3) along surface on side. (5) composed plate-shaped flexible material side such that at least (5c) (1c) (1).
