PROBLEM TO BE SOLVED: To improve a frequency of a head by immediately suppressing a residual pressure of ink generated when a plurality of nozzles are driven at the same time. SOLUTION: This inkjet head is so constituted that the plurality of inkjet nozzles each consisting of an orifice, an ink chamber, a restrictor and a second ink chamber are juxtaposed and the rear faces of the inkjet nozzles are communicating with a common ink path with a filter therebetween. An ink supply path for supplying ink from the external section is provided to one end of the common ink path and a low rigid ink channel section having a low rigidity is formed at the other end of the common ink path so as to suppress a pressure propagation speed of the ink. The end section of the low rigid ink channel section is sealed. COPYRIGHT: (C)2005,JPO&NCIPI
