Abstract
A liquid container comprises an inner wall that forms the liquid containing portion to contain liquid therein; an outer wall that forms the container to contain the liquid containing portion therein; and a liquid supply portion for supplying liquid from the liquid containing portion to the outside. Then, the inner wall is arranged to be a member to generate negative pressure in the liquid containing portion by being deformed following the leading-out of the liquid, and also, formed by the material having an elastic modulus change of 25% or less against the temperature change of use environment. With the liquid container thus structured, it is possible to implement the stable supply of liquid by stabilizing the characteristic of negative pressure in the liquid containing portion thereof irrespective of the temperature changes of use environments.
