Abstract
An ink-jet head and its manufacturing method and an ink-jet recording device, which condense a color component in an ink with the color dissipated in a solvent, and record with the ink flown toward a record medium. A protruded-type electrode and its leading electrode are formed on a supporting substrate. An ink-guide-groove which is formed from the bottom section to the pointed end portion on the wall surface, is provided at the protruded-type electrode. A connected portion by the protruded-type electrode of the leading electrode and an end portion of an opposite portion are exposed outward. A plurality of protruded-type electrodes are provided on the supporting substrate along main scanning direction X. The shape of the protruded-type electrode is pyramid, and its pointed end portion is sharpened. Ink guide grooves are formed on each wall surface of the pyramid of the protruded-type electrode. A width of the ink guide groove becomes narrower as the distance to the pointed end portion decrease from the bottom portion.
