Abstract
There is provides liquid discharging apparatus including: head having nozzle; reservoir configured to store the liquid such that liquid surface is positioned higher than opening of the nozzle in a state that the reservoir stores the liquid of maximum storable amount; and atmosphere port connecting gas layer and outside of the reservoir. Inner diameter d of the nozzle and head difference h satisfy expression of ρhd/σ cos θ≤4/g, provided that p is specific weight of the liquid, σ is surface tension of the liquid, θ is contact angle of the liquid in the nozzle and g is gravitational acceleration, the head difference h being difference in height between meniscus in the opening of the nozzle and the liquid surface in the state that the reservoir stores the liquid of the maximum storable amount.
