摘要
According to an embodiment, an ink jet head (liquid ejecting head) includes an actuator plate and a cover plate (see FIG. 8). As illustrated in FIG. 1, channel grooves for a discharge channel (ejection channel) and a non-discharge channel (non-ejection channel) in a Z-direction are formed on a front surface of the actuator plate, so as to be alternately arranged in an X-direction, by cutting with a dicing blade or the like. The discharge channel and the non-discharge channel are formed to have a groove width W of smaller than 70 μm, in order to correspond to high density of nozzles. In the embodiment, the discharge channel and the non-discharge channel are formed to have a groove width of 55 μm, 50 μm, or 40 μm, for example.
