PROBLEM TO BE SOLVED: To allow prevention of flowing-out of bubbles generated inside without reducing the amount of a liquid to be contained.SOLUTION: A first liquid chamber into which an air flow inlet is opened and a second liquid chamber which is separated from the first liquid chamber by a partition and into which a liquid flow outlet is opened are provided in a liquid container. The partition has an almost horizontal first partition part, and a second partition part facing more upward than the first partition part. A first communication port is provided in the first partition part and a second communication port is provided in the second partition part or in a boundary line between the second partition part and a ceiling of the first liquid chamber. Thus, since generation of new bubbles through the second communication port can be suppressed and drawing-in of the bubbles through the first communication port can be suppressed, flowing-out of the bubbles from the second liquid chamber can be prevented. In addition, since it is not necessary to contain a negative pressure generation member in the liquid chamber by preventing flowing-out of the bubble, it never occurs that the amount of the liquid contained in the liquid chamber is reduced. |
