Abstract
An ink recording apparatus used with printers or the like and manufactured by applying semiconductor device manufacturing techniques. One wall of an ink chamber is formed of a single-crystal substrate and an ink jet port is formed by etching on the single-crystal substrate. A slider and electrodes composed of polycrystalline-silicon film are formed on the single-crystal substrate by film forming in the LPCVD method and patterning through plasma etching. The slider has a plurality of ink passing holes which have respectively different diameter, being driven by electrostatic attracting force produced between voltage-applied electrodes and the slider. The electrodes are formed at positions corresonding to those where the each ink passing hole is aligned with the ink jet port.
