摘要

A liquid supply system includes a liquid supply container provided with a liquid accommodating portion being deformable by storing liquid in the closed space to be able to generate negative pressure, a liquid supply unit detachably mountable on the liquid supply container to contain the capillary force generating material retaining liquid therein, and at the same time, to supply liquid to the outside, a container for the capillary force generating material provided with an air communication unit communicating with the air outside to be able to generate the gas-liquid exchange for leading out liquid by introducing gas into the liquid accommodating portion through the communication unit connected with the liquid supply container, and the communication unit being arranged on the upper surface of the container for the capillary force generating material, at the same time, the liquid supply container being arranged above the container for the capillary force generating material through the communication unit to shaft liquid in the liquid supply container to the container for the capillary force generating material.
