description	To provide a head chip that can suppress floating capacitance and improve image quality, and a manufacturing method for the same, a liquid jet head as well as a liquid jet recording device.SOLUTION: The head chip comprises an actuator plate 42 that applies pressure to liquid, which jets liquid. The actuator plate includes: a front surface; a rear surface; a channel extending in a given direction which has a first opening provided on the front surface and a second opening, provided on the rear surface, whose length in the given direction is shorter than a length of the first opening; an electrode that has a front surface-side part Edc-u provided at a side wall of the channel near the first opening and a rear surface-side part Edc-d provided at a side wall at the second opening side rather than the front surface-side part, which is identical in size in the given direction to the front surface-side part or is larger in size than the front surface-side part.SELECTED DRAWING: Figure 7 【課題】浮遊容量を抑え、画質を向上させることが可能なヘッドチップおよびその製造方法、液体噴射ヘッド、ならびに液体噴射記録装置を提供する。【解決手段】ヘッドチップは、液体に圧力を印加するアクチュエータプレート４２を備え、液体を噴射する。アクチュエータプレートは、表面および裏面と、所定の方向に延在し、かつ、表面に設けられた第１開口と、裏面に設けられるとともに、所定の方向の長さが第１開口よりも短い第２開口とを有するチャネルと、第１開口側のチャネルの側壁に設けられた表面側部分Ｅｄｃ−ｕと、表面側部分よりも第２開口側の側壁に設けられるとともに所定の方向の大きさが表面側部分と同じまたは表面側部分よりも大きい裏面側部分Ｅｄｃ−ｄとを有する電極とを含んでいる。【選択図】図７
