PROBLEM TO BE SOLVED: To clean a tool surface of a molding tool or improve releasability between a molded article and the molding tool by using a mobile atmospheric pressure plasma processing apparatus, without removing the molding tool of a resin molding apparatus.SOLUTION: A mobile atmospheric pressure plasma processing apparatus 11 constituted separately from a resin molding apparatus 1, includes: a plasma irradiation unit 14 provided with a plasma irradiation part 13; a drive mechanism 15; a high frequency power source 16; a plurality of gas supply mechanisms 22, 23, 24; and an exhaust mechanism 18, etc. The atmospheric pressure plasma processing apparatus 11 is moved to the periphery of the resin molding apparatus 1, and the plasma irradiation unit 14 is brought close to or tightly adhered to the tool surface of a molding tool of the resin molding apparatus 1 by the drive mechanism 15. The tool surface of the molding tool is irradiated with plasma under the atmospheric pressure state by supplying gas to the plasma irradiation part 13 provided in the plasma irradiation unit 14 and applying high frequency voltage to the plasma irradiation part 13. 【課題】移動式の大気圧プラズマ処理装置を用いて、樹脂成形装置の成形型を取り外すことなく、成形型の型面をクリーニングする、又は、成形品と成形型との離型性を向上させる。【解決手段】樹脂成形装置１とは別に構成された移動式の大気圧プラズマ処理装置１１において、プラズマ照射部１３を設けたプラズマ照射ユニット１４、駆動機構１５、高周波電源１６、複数のガス供給機構２２、２３、２４、排気機構１８等を備える。大気圧プラズマ処理装置１１を樹脂成形装置１の周辺に移動させ、駆動機構１５によってプラズマ照射ユニット１４を樹脂成形装置１の成形型の型面に近接又は密着させる。プラズマ照射ユニット１４内に設けたプラズマ照射部１３にガスを供給して高周波電圧を印加することによって、大気圧状態でプラズマを成形型の型面に照射する。【選択図】図３
