PROBLEM TO BE SOLVED: To make high in the density of electric wirings in a liquid droplet discharging head in which a plurality of piezoelectric bodies are arranged for one nozzle. SOLUTION: One side 70A of each of the plurality of piezoelectric bodies 70 is electrically connected to a drive circuit 82 in common through the electric wring 72. Thus, the number of wirings connecting the piezoelectric body 70, and the drive circuits 82 and 83 is reduced to about 1/2 of that in constitution where they are all connected individually because it is the number of lines connected in common in addition to lines connected individually. Therefore, the high density of the electric wirings is contrived. COPYRIGHT: (C)2009,JPO&INPIT
