摘要： A drying device includes a drier, a gas circulator, and a concentration adjuster. The drier warms a liquid composition on a drying target object. The gas circulator circulates a gas containing a volatile component of an organic solvent warmed and volatilized by the drier to reuse the gas for drying. The concentration adjuster adjusts a concentration of the volatile component reused.
