发明名称 Ink jet type printer head
摘要 An ink jet type printer head is provided which can be simply assembled and in which malfunctions such as leak of ink, peeling-off of members or the like making up the ink jet type printer head are reduced. Grooves going around along a corresponding position inside a space portion of each of pressure chambers are formed on a surface of one piece of a piezoelectric element plate to partition the piezoelectric element plate and each portion of the piezoelectric element plates partitioned by these grooves acts as a piezoelectric element for each of the pressure chambers. Since a non-moving section having the same thickness as that of the piezoelectric elements among piezoelectric elements is formed, a vibrating plate can be firmly fixed to pressure chamber plate containing a partitioning wall portion between pressure chambers.
