Abstract
An ink jet head unit including a head () in which a plurality of nozzle arrays () are formed. Each of the nozzle arrays has a number of nozzle holes, and ink can be ejected from the nozzle holes. The head () is mounted on the head base, and flat cables () are connected at one end to mounting parts (), which are interposed between a first pair of the nozzle arrays () and a second pair of the nozzle arrays (). The flat cables are flexibly formed by covering transmission wires with an insulation film. The flat cables are connected to the head to transmit ink ejection signals for driving the head.
