To provide a chemical analyzer provided with a hollow fiber deaeration module that can maintain its original good deaeration performance even during long-term continuous use, and in addition, can suppress growth of germs or the like.SOLUTION: A hollow fiber deaeration module 20A has a housing 210, and hollow fiber membranes 220 arranged in an internal space S1 of the housing. The housing 210 has: a liquid supply unit 216A that connects an outside of the housing 210 and internal spaces S2 of the hollow fiber membranes 220 to each other, and supplies constant-temperature water W1 to the internal spaces S2 of the hollow fiber membranes 220 from the outside of the housing 210; a liquid discharge unit 217A that connects the internal spaces S2 of the hollow fiber membranes 220 and the outside of the housing 210 to each other, and discharges the deaerated constant-temperature water W2 to the outside of the housing 210 from the internal spaces S2 of the hollow fiber membranes 220; and a gas discharge unit 218A that connects the internal space S1 of the housing 210 and the outside of the housing 210 to each other, and reduces a pressure in the internal space S1 of the housing 210. The gas discharge unit 218A is provided at a lower end part in a vertical direction of the housing 210.SELECTED DRAWING: Figure 2 【課題】長時間の連続使用でも本来の良好な脱気性能を維持することができ、加えて菌等の繁殖を抑制することができる中空糸脱気モジュールを具備した化学分析装置を提供する。【解決手段】中空糸脱気モジュール２０Ａは、筐体２１０と、該筐体の内部空間Ｓ１に配置された中空糸膜２２０とを有する。筐体２１０は、筐体２１０の外部と中空糸膜２２０の内部空間Ｓ２とを接続し、筐体２１０の外部から中空糸膜２２０の内部空間Ｓ２に恒温水Ｗ１を供給するための液体供給部２１６Ａと、中空糸膜２２０の内部空間Ｓ２と筐体２１０の外部とを接続し、中空糸膜２２０の内部空間Ｓ２から筐体２１０の外部に脱気された恒温水Ｗ２を排出するための液体排出部２１７Ａと、筐体２１０の内部空間Ｓ１と筐体２１０の外部とを接続し、筐体２１０の内部空間Ｓ１を減圧するための気体排出部２１８Ａとを有する。気体排出部２１８Ａは、筐体２１０の鉛直方向下端部に設けられる。【選択図】図２
