Abstract
A liquid container includes a negative pressure generating member containing chamber which contains therein a negative pressure generating member formed of a fiber material and provided with a liquid supplying portion and an atmosphere communication portion. A liquid containing chamber, provided with a communicating portion communicating with the negative pressure generating member containing chamber, forms a substantially hermetically sealed space and stores therein liquid to be supplied to the negative pressure generating member. A partition wall for partitioning the negative pressure generating member containing chamber and the liquid containing chamber and forming the communicating portion, is provided with a gas introduction blocking unit which cooperates with the partition wall and the liquid contained in the negative pressure generating member containing chamber to block the introduction of gas from the communicating portion into the liquid containing chamber, except during the supply of the liquid from the liquid supplying portion to the outside.
