Abstract
A common joining electrode and arrays of island-shaped individual joining electrodes are formed on a substrate of a flexible flat cable, which is connected to a recording head. The common joining electrode extends in the X direction along the periphery of the cable board. The individual joining electrodes are arranged in a staggered manner in a region surrounded by the common joining electrode. The wiring of the individual joining electrodes is patterned so that the gap between the common joining electrode and a wiring connected a nearest individual joining electrode to the common joining electrode is larger than the gap between the common joining electrode and the nearest individual joining electrode. In locations where wirings are closed to one another, it is possible to realize a fine wiring density without excessively narrowing the gaps between adjoining wirings and between the wirings and the side edges of the common joining electrode.
