Provided is an ink-jet apparatus that: has a wide control range of the direction for ink ejection; can correct a variation in the direction for ink ejection; and can improve the yield of a product when used for manufacture of electronic devices. The ink-jet apparatus includes: pressure chamber 110 configured with a pair of partition walls 111; nozzle plate 101 having nozzle 100; diaphragm 112 supported by partition walls 111; piezoelectric elements 131 and 132 that are in contact with diaphragm 112 for pressurizing pressure chamber 110; and piezoelectric elements 141, 142 and 143 supporting partition walls 111. A voltage can be applied individually to piezoelectric elements 131, 132, and 141 to 143. The widths of part A and part B of diaphragm 112, part A being in contact with a piezoelectric element, and part B being in contact with partition wall 111 satisfy a particular relationship. |
