摘要：
An ink jet head comprises a plurality of ink liquid paths in which energy generating elements are formed, a common liquid chamber communicated with the plurality of ink liquid paths, and an air chamber which is communicated with the common liquid chamber via a communication section formed at substantially a central portion of the air chamber and which ls formed along the longitudinal direction of the common liquid chamber. This arrangement of the ink jet head enables air in the air chamber to act on refilling behavior of ink in each of the ink liquid paths so that refilling in each of the ink liquid paths is not delayed.
