ABSTRACT:
A head unit has a head main body for discharging ink, a driver IC and an FPC, which is interposed between the driver IC and the head main body. The FPC has through holes each of which is embedded with a conductor. The conductor is bonded to an output terminal of the driver IC and the separate electrode formed on a piezoelectric sheet of the head main body. Thus, the driver IC is connected electrically to the separate electrodes of the head main body. With this arrangement, the heat generated by the driver IC is prevented from propagating to the head.
