A recording head where an actuator, a cavity portion and a flexible flat cable are placed one on another is provided in a head holder of a carriage. A drive IC chip is mounted on the flexible flat cable. A bottom plate portion of a first heat sink is in contact with the drive IC chip so as to be thermally conductable, and a side plate portion thereof is disposed in a standing condition. A base end of a second heat sink is in contact, so as to be thermally conductable, with a wiring pattern formed portion of the flexible flat cable between the drive IC chip and the actuator, and a heat dissipating portion of the second heat sink is extended below the bottom plate portion, and a part of the heat dissipating portion is exposed to the outside of the head holder.
