Title: Ink jet type printer head

Abstract: An ink jet type printer head is provided which can be simply assembled andin which malfunctions such as leak of ink, peeling-off of members or thelike making up the ink jet type printer head are reduced. Grooves goingaround along a corresponding position inside a space portion of each ofpressure chambers are formed on a surface of one piece of a piezoelectricelement plate to partition the piezoelectric element plate and eachportion of the piezoelectric element plates partitioned by these groovesacts as a piezoelectric element for each of the pressure chambers. Since anon-moving section having the same thickness as that of the piezoelectricelements among piezoelectric elements is formed, a vibrating plate can befirmly fixed to pressure chamber plate containing a partitioning wallportion between pressure chambers.
