PROBLEM TO BE SOLVED: To provide a liquid jetting head made small by arranging a circuit board in a compact form. SOLUTION: A passage unit 17 of a flat shape including a nozzle plate 22, a pressure generation chamber 26 for pressurizing a liquid by a pressure generating means 30, and a liquid storage chamber 23 for storing the liquid to be supplied to the pressure generation chamber 26 is joined to a head case 15 in a state with a space 15f formed in the head case 15. Moreover, the liquid jetting head 1 is equipped with the circuit board 18 where an operation signal circuit of the pressure generating means is set, and a flexible cable 19 for inputting an operation signal to the pressure generating means 30 by connecting the circuit board 18 and the pressure generating means 30 with each other. The circuit board 18 is arranged so that a connection joining part 36 between the circuit board 18 and the flexible cable 19 enters the interior of the space 15f. Accordingly, the circuit board 18 is accommodated in the space 15f in a state of tilting and dimensions of the head case 15 can be made small. COPYRIGHT: (C)2005,JPO&NCIPI
