A liquid storing container attachable and detachable to and from a recording device includes a negative pressure producing member storage chamber which has a bottom wall and opposed side walls and which accommodates a negative pressure producing member and is equipped with a liquid supplying section in the bottom wall and an atmosphere communication section. A partition wall separates the negative pressure producing member storage chamber from a liquid storage chamber and defines a communicating hole for establishing communication therebetween. A path in the vicinity of the communicating hole on the negative pressure producing member storage chamber side introduces the atmosphere from the negative pressure producing member storage chamber into the liquid storage chamber. The negative pressure producing member is made with a fiber material having directionality and the communication hole is offset from the bottom wall.
