Abstract
Provided is a liquid-jet apparatus which can suppress liquid consumption by preventing air that can turn into bubbles from entering a liquid introducing columnar body in replacement of a liquid storage member and thus reducing a frequency of execution of a cleaning operation for discharging the bubbles inside a liquid passage. An ink introducing needle in a printer includes: a needle-like protrusion having a tapered portion whose diameter is gradually increased toward its base from its tip; and a straight portion formed linearly and continuously from the tapered portion. In the tapered portion of the needle-like protrusion in the ink introducing needle, groove portions extending to an edge portion of the tapered portion are provided.
