1. A head chip comprising:
an actuator plate in which a jet channel extending in a first direction and a non-jet channel extending in the first direction are alternately arranged in a second direction crossing the first direction;
an intermediate plate which is overlapped with the actuator plate in a third direction perpendicular to the first direction and the second direction, and is provided with a communication hole communicated with the jet channel, and a through hole communicated with the non-jet channel; and
a jet orifice plate which is overlapped with the intermediate plate at an opposite side to the actuator plate in the third direction in a state of closing the through hole, and is provided with a jet orifice which is communicated with the communication hole, from which liquid contained in the jet channel is jetted, and which is formed at a position corresponding to the jet channel, wherein
the non-jet channel is communicated with an outside of the head chip, and
the through hole is disposed at an inner side in the second direction of inner surfaces extending in the first direction of the non-jet channel, viewed from the third direction.
