摘要：
A discharge device is provided. The discharge device includes a liquid feed-discharger, and the liquid feed-discharger includes a feed unit configured to feed a liquid and a discharge unit having discharge holes configured to discharge the liquid fed by the feed unit. A ratio (X/Y) of a maximum cross-sectional area X (mm2) to a minimum cross-sectional area Y (mm2) of the liquid feed-discharger in a direction orthogonal to an axial direction of the liquid feed-discharger is from 1 to 5.
