PROBLEM TO BE SOLVED: To provide a discharge device such that the discharge electrode is difficult to be touched with a finger and easily cleaned.SOLUTION: A discharge device comprises: a casing 40； a substrate 31 that is housed into an inner part of the casing 40； discharge electrodes 11 and 12 that are held to the substrate 31 so that a tip part is projected to an outer part of the casing 40 and generates a discharge； an insulation sealing part M that insulates and seals the substrate 31 in the inner part of the casing 40； and an electrode protection part 20 for protecting the discharge electrodes 11 and 12 in the outer part of the casing 40. In the casing 40, a tip part side of the discharge electrodes 11 and 12 is inserted, and an opening part 44 sealed by the insulation sealing part M is provided. The electrode protection part 20 is provided so as to be more projected from the tip part of the discharge electrodes 11 and 12 from the casing 40, and includes a first protection part 21 and a second protection part 22 which are opposite with an interval on both sides of the discharge electrodes 11 and 12. A root side of a shaft center part of the electrode protection part 20 is sealed with the insulation sealing part M.SELECTED DRAWING: Figure 3【課題】放電電極に指が触れにくくするとともに、放電電極の清掃を容易に行うことが可能な放電装置を提供する。【解決手段】放電装置は、筺体４０と、筺体４０の内部に収容される基板３１と、先端部が筺体４０の外部に突出するように基板３１に保持され、放電を発生させる放電電極１１，１２と、筺体４０の内部で基板３１を絶縁封止する絶縁封止部Ｍと、筺体４０の外部で放電電極１１，１２を保護するための電極保護部２０と、を備え、筺体４０には、放電電極１１，１２の先端部側が挿通され、絶縁封止部Ｍで封止される開口部４４が設けられ、電極保護部２０は、筺体４０から放電電極１１，１２の先端部よりも突出して設けられ、放電電極１１，１２の両側で互いに間隔を設けて対向する第１保護部２１および第２保護部２２を有する。電極保護部２０の軸心部の根元側は絶縁封止部Ｍで封止される。【選択図】図３
