A photosensitive polyimide resin 12 is exposed and developed via a computer-aided designed pattern film 14 to form a pattern onto a mold base 11 by means of photoresisit method. A head has a nozzle member in which a plurality of nozzles are formed, a pressure chamber wall member in which a plurality of pressure chambers are formed, and piezoelectric type actuators that have a diaphragm and a plurality of piezo elements and apply pressure to each of the plurality of pressure chambers for ejecting ink from the nozzles. Two lines of substantially equal length are selected in the intermediate zone to be cut simultaneously every time the two cutting blades have been moved line-to-line distance for indexing. The antenna may operate in multiple communications bands.
