Claim 0:
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 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 actuator plate comprises a blocking part disposed between the non-jet channel and the jet orifice plate, the blocking part and the actuator plate being formed as one piece,
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

a flow channel member overlapped in a thickness direction crossing the second direction viewed from the first direction in the actuator plate, wherein:
the opposed surface is a surface of the actuator plate which faces to the first direction, and
the flow channel member includes
a circulation channel which is provided to a portion located between the non-jet channel and the opposed surface in the first direction, and is individually communicated with the jet channel,
an entrance flow channel which is provided to a portion located at an opposite side to the opposed surface in the first direction with respect to the circulation channel, and is communicated with the jet channel, and
an exit flow channel communicated with a plurality of circulation channels.
