Patent attributes
At least one liquid channel has a channel area larger than a channel area of the at least one nozzle. A nozzle plate is formed with the at least one nozzle and includes a piezoelectric section. The nozzle plate has a first surface and a second surface opposite the first surface. A channel structure member is fixed to the nozzle plate and is formed with the at least one liquid channel. A first electrode is provided on the first surface. At least part of the first electrode is arranged in a nozzle peripheral region of the at least one nozzle. A second electrode is provided on the second surface. At least part of the second electrode is arranged in the nozzle peripheral region of the at least one nozzle. An energy applying section applies ejection energy to liquid in the at least one liquid channel.
