Provided is a discharge device capable of improving the generation efficiency of active species. The discharge device has a tip (15A), a discharge section (11) to which a voltage is applied to discharge from the tip (15A), and an induction electrode (13) for forming an electric field between the discharge section (11). ) And a second electrode (50) disposed between the discharge part (11) and the induction electrode (13), to which a voltage having the same polarity as that of the discharge part (11) is applied.活性種の発生効率を向上できる放電装置を提供する。放電装置は、先端部（１５Ａ）を有し、電圧が印加されて先端部（１５Ａ）から放電する放電部（１１）と、放電部（１１）との間に電界を形成する誘導電極（１３）と、放電部（１１）と誘導電極（１３）との間に配置され、放電部（１１）と同じ極性の電圧が印加される第２の電極（５０）とを備えている。
