Zusammenfassung:	To provide a PAI solution capable of manufacturing a polyamide-imide (PAI) belt having excellent thickness uniformity and excellent mechanical characteristics, and to provide a method of manufacturing the PAI belt using the same.SOLUTION: (1) Disclosed is a PAI solution for belt molding, which is a solution containing trimellitic acid as an acid component and PAI using an o-tolidine diisocyanate as an isocyanate component, whose viscosity is 60 Pa s or more and 200 Pa s or less, and whose concentration is more than 15 mass% and less than 25 mass%. (2) Disclosed is a method of manufacturing a PAI belt which is characterized in that the PAI solution is applied to a cylindrical mold and the cylindrical mold is demolded after being dried.SELECTED DRAWING: None 【課題】良好な厚み均一性を有し、かつ力学的特性が良好なポリアミドイミド（ＰＡＩ）ベルトが作成できるＰＡＩ溶液およびこれを用いたＰＡＩベルトの製造方法の提供。【解決手段】＜１＞酸成分としてトリメリット酸、イソシアネート成分としてｏ－トリジンジイソシアネートを用いたＰＡＩを含む溶液であって、粘度が６０Ｐａ・ｓ以上、２００Ｐａ・ｓ以下であり、濃度が１５質量％超、２５質量％未満であるベルト成形用ＰＡＩ溶液。＜２＞前記ＰＡＩ溶液を、円筒状金型に塗布、乾燥後、脱型することを特徴とするＰＡＩベルトの製造方法。【選択図】なし
