description	There are provided a head chip and a method of manufacturing the same, a liquid jet head, and a liquid jet recording device each capable of suppressing a stray capacitance to improve the image quality. The head chip according to an embodiment of the present disclosure is a head chip having an actuator plate adapted to apply pressure to liquid to jet the liquid. The actuator plate includes an obverse surface and a reverse surface, a channel extending in a predetermined direction and having a first opening provided to the obverse surface and a second opening which is provided to the reverse surface and is shorter in length in the predetermined direction than the first opening, and an electrode having an obverse surface side part disposed on a sidewall of the channel on the first opening side, and a reverse surface side part which is disposed on the sidewall closer to the second opening than the obverse surface side part and is one of equal to and larger than the obverse surface side part in size in the predetermined direction.
