<p>A liquid tank according to the present invention comprises negative-pressure introducing sections (38, 40a, and 40b) for introducing negative pressure into the liquid tank, a liquid intake section (43) for taking a liquid in the liquid tank on the basis of the negative pressure introduced by the negative-pressure introducing sections (38, 40a, and 40b), an atmosphere communication port (39) that is closed when the liquid is introduced through the liquid intake section (43), and a gas-liquid separating element (44) disposed in the negative-pressure introducing sections so as to pass through only a gas. The gas-liquid separating element (44) has a joined portion formed at least on the outer periphery of the gas-liquid separating element (44) and joined to he negative-pressure introducing sections (38, 40a, and 40b), and a ventilation area that contributes to ventilation. <IMAGE></p> |
