PROBLEM TO BE SOLVED: To provide an extracorporeal circulation module having a cylindrical container in which thinning is possible while maintaining strength and performance.SOLUTION: An extracorporeal circulation module includes a resin-made cylindrical container and a pair of fluid ports in an outer circumferential surface at both ends of the cylindrical container. Both of the two injection-molded gates are disposed on the body outer circumferential surface of the cylindrical container and on the straight line in the central axis direction. An interval P of the injection-molded gate of the two places and a cylindrical container length L are represented by a relational expression. The wall thickness in the center of the body part of the cylindrical container is 1.0 mm or more and 2.5 mm or less.SELECTED DRAWING: Figure 2 【課題】強度や性能を維持しつつ、薄肉化が可能な円筒容器を有した体外循環用モジュールを提供する。【解決手段】樹脂製円筒容器と、該円筒容器両端部外周面に一対の流体ポートを備え、該円筒容器の胴部外周面に２箇所の射出成形ゲートを備え、該２箇所の射出成形ゲートがいずれも、該円筒容器の胴部外周面上で中心軸方向の一直線上に配置され、該２箇所の射出成形ゲートの間隔Ｐと該円筒容器長さＬが関係式で表され、該円筒容器の胴部中央における肉厚が１．０ｍｍ以上、２．５ｍｍ以下である体外循環用モジュールである。【選択図】図２
