Zusammenfassung:	To provide a catheter assembly capable of suppressing turn-up of an end of a catheter when the catheter is inserted and when a dilator is removed.SOLUTION: A catheter assembly 10 includes a catheter 16 and a dilator 14. In a non-assembly state that the catheter 16 and the dilator 14 are not assembled, an inner diameter of a catheter side tapered part 26 of the catheter 16 is an outer diameter or smaller of a dilator side base part 46 of the dilator 14. The dilator 14 has a recess 48 where liquid can flow in on the outer peripheral surface of a part in contact with an inner peripheral surface 26a of the catheter 16 in an assembled state.SELECTED DRAWING: Figure 2 【課題】カテーテルの挿入時とダイレータの抜去時の両方でカテーテルの先端のめくれを抑制することができるカテーテル組立体を提供する。【解決手段】カテーテル組立体１０は、カテーテル１６と、ダイレータ１４とを備える。カテーテル１６とダイレータ１４が組み付けられていない非組付状態で、カテーテル１６のカテーテル側テーパ部２６の内径は、ダイレータ１４のダイレータ側基部４６の外径以下である。また、ダイレータ１４は、組付状態で、カテーテル１６の内周面２６ａに接する部分の外周面に液体が流入可能な凹部４８を有する。【選択図】図２
