摘要：
A liquid jetting device includes a plurality of liquid passages each having a liquid ejecting element and communicating with an ejection hole, a common liquid chamber communicating with each of the plurality of liquid passages and an air bubble introducer for making a non-disappearable air bubble formed by thermal energy exist in the common liquid chamber before a start of liquid ejection. The liquid is allowed to be ejected in the presence of the air bubble. The non-disappearable air bubble functions as a buffer to absorb pressure during discharge to restrict flow of the ink in the direction opposite to the discharge port.
