ABSTRACT:
A liquid jetting head of the invention includes a flowing-path plate through which a flowing-path space is formed as a flowing-path for a liquid. A nozzle plate is provided on one side surface of the flowing-path plate, said nozzle plate having a nozzle that is communicated with the flowing-path space. A sealing plate is provided on the other side surface of the flowing-path plate for sealing the flowing-path space. A portion of the other side of the flowing-path space forms a pressure-chamber space. A portion of the other side of the flowing-path plate including at least a portion of the pressure-chamber space is formed by electrocasting. A pressure-generating unit is provided at a portion of the other side of the sealing plate corresponding to the pressure-chamber space for changing a pressure of the liquid in the pressure-chamber space.
