Abstract

A liquid discharge apparatus (1000) has a liquid discharge head (3) having a recording element board (10) including discharge orifice (13) discharging liquid, pressure chambers (23) internally provided with a recording element (15) generating energy to discharge liquid, the pressure chambers (23) each communicating with the discharge orifices (13) via discharge channels, a liquid supply channel (18) supplying liquid to the pressure chamber (23), a liquid recovery channel (19) recovering liquid from the plurality of pressure chambers (23), and a tank storing liquid supplied to the liquid discharge head (3). The pressure chambers (23) communicate between the liquid supply channel (18) and the liquid recovery channel (19) so that liquid flows through the pressure chambers (23), and the specific permittivity µ r of the liquid stored in the tank satisfies the relationship of µ r ¤ 40.7.
