Abstract:
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.

Claim (Index 10):
The manufacturing method of a liquid ejecting head chip according to  claim 9 , further comprising:\n a roughening step of roughening an exposed surface of the actuator plate, after the channel groove forming step, wherein, in the channel groove forming step, the channel groove is formed to have a width of smaller than 70 \u03bcm, and in the electrode forming step, the electrode having a film thickness of 0.5 \u03bcm or smaller is formed by forming a plating film, after the roughening step.
