Claim 5:
6. 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 arranged alternately in a second direction crossing the first direction;
a jet orifice plate which has a jet orifice communicated with the jet channel, and faces the actuator plate, wherein:
the non-jet channel is terminated at a position separated from an opposed surface to the jet orifice plate in the actuator plate, and
the jet channel opens on the opposed surface; and

wherein an end surface of the non-jet channel at the opposed surface side includes:
a first inclined surface extending in a direction of getting away from the opposed surface in the first direction as getting away from a first surface facing to a thickness direction crossing the second direction viewed from the first direction, in the actuator plate, and
a second inclined surface which gets away from the opposed surface in the first direction as getting away from a second surface located oppositely to the first surface in the thickness direction, in the actuator plate, and connects to the first inclined surface.
