In a configuration having an ink containing portion (10) which is deformable at least in a part (11) thereof, a spring (40) for generating a required negative pressure in the container by exerting a force that expands the deformable part, and an air introducing section (16) for allowing air to be introduced in accordance with an increase in the negative pressure in the container to keep the negative pressure in an adequate range, a one-way valve (30) is used to prevent leakage of ink from a sealed containing space (S) containing ink to the outside and to allow introduction of air into the containing space from the outside. As a result, there is provided an ink tank from which no ink leaks out through the air introducing section thereof in any ambience for use or storage and which can maintain stable negative pressure characteristics regardless of the phase of the consumption of the liquid.
