摘要

To suppress the increase in concentrations of metal impurities, particles, and water in a nanoimprint liquid contained in a containing part with time.SOLUTION: A liquid discharging device 1 comprises: a containing part 8 for containing a nanoimprint liquid 9; and a discharge opening 10 communicating with the containing part 8 and serving to discharge the nanoimprint liquid 9. The liquid discharging device 1 has, in the containing part 8, an adsorbing/absorbing body 23 for adsorbing or absorbing at least one kind selected from a group consisting of particles, metal ions and water. The liquid discharging device is arranged so that the adsorbing/absorbing body 23 is never discharged from the discharge opening 10 when discharging the nanoimprint liquid 9 from the discharge opening 10.SELECTED DRAWING: Figure 1
