Abstract
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 chamberconfigured with a pair of partition walls; nozzle platehaving nozzle; diaphragmsupported by partition walls; piezoelectric elementsandthat are in contact with diaphragmfor pressurizing pressure chamber; and piezoelectric elementsandsupporting partition walls. A voltage can be applied individually to piezoelectric elements, andto. The widths of part A and part B of diaphragm, part A being in contact with a piezoelectric element, and part B being in contact with partition wallsatisfy a particular relationship.
