PROBLEM TO BE SOLVED: To provide a liquid jetting apparatus decreasing the number of performing times of a cleaning operation for venting air bubbles in a liquid flow path and suppressing the consumption of a liquid by suppressing the ingression of air to become the air bubbles into a liquid introducing needle when replacing a liquid storing member. SOLUTION: An ink introducing needle 21 in a printer is equipped with a needle-like projecting part 23 with a tapered part 48 whose diameter is gradually enlarged from a distal end to a proximal end side, and a straight part 51 straightly continuously formed from the tapered part 48. A channel part 54 is provided in the tapered part 48 of the needle-like projecting part 23 of the ink introducing needle 21 along the breaking direction X of a sealing film 46 of an ink cartridge and reaching an edge part of the tapered part 48.
