Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a tube molding for a catheter shaft excellent in kink resistance and pushability, and to provide a catheter using the same.SOLUTION: There is provided a tube molding for a catheter shaft formed of a polyimide resin composed of an acid component and a diamine component. The tube molding for the catheter shaft is formed of the polyimide resin composed of the acid component represented by general formula (1) and the diamine component containing 50-85 mol% of aromatic diamine represented by general formula (2) (in the formula, R represents a hydrogen atom, a methyl group, a hydroxy group or a halogen atom). There is also provided a catheter having the tube molding for the catheter shaft.SELECTED DRAWING: Figure 2 【課題】キンク性とプッシャビリティに優れたカテーテルシャフト用チューブ成型体、及び、これを用いたカテーテルを提供する。【解決手段】酸成分とジアミン成分からなるポリイミド樹脂で形成された、カテーテルシャフト用のチューブ成型体であって、前記酸成分が下記一般式（１）で表され、前記ジアミン成分が下記一般式（２）で表される芳香族ジアミン（式中、Ｒ水素原子、メチル基、ヒドロキシ基又はハロゲン原子を表す。）を前記ジアミン成分中に５０〜８５モル％の割合で含有するカテーテルシャフト用チューブ成型体、並びに、このカテーテルシャフト用チューブ成型体を備えたカテーテル。【選択図】図２
