Abstract
According to an embodiment, a liquid ejecting head chip includes an actuator plate and an in-channel electrode. In the actuator plate, a plurality of channels are arranged at a distance in an X-direction. Each of the channels includes an extension portion and a raise-and-cut portion. The extension portion extends in a Z-direction. The raise-and-cut portion continues from the extension portion toward one side of the Z-direction and has a groove depth which is gradually reduced toward the one side of the Z-direction. The in-channel electrode is formed on an inner surface of each of the channels, with a plating film.

A liquid ejecting head chip comprising:
- an actuator plate in which a plurality of channels are arranged at a distance in a second direction which is orthogonal to a first direction, and of which each includes an extension portion and a raise-and-cut portion, the extension portion extending in the first direction, and the raise-and-cut portion continuing from the extension portion toward one side of the first direction and having a groove depth which is gradually reduced toward the one side of the first direction;
- and
- an in-channel electrode which is formed on an inner surface of each of the channels with a plating film;
- wherein the plurality of channels include ejection channels and non-ejection channels which are alternately arranged at a distance in the second direction, and wherein both of the ejection channels and non-ejection channels include the raise-and-cut portions.
