Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a double lumen catheter capable of being connected to a blood circuit by a simple operation, causing no liquid leaking or no air infiltrating in connecting with the blood circuit and advantageous in a cost. SOLUTION: A double lumen catheter is composed of a catheter main body 1 having a blood supply lumen 11 and a blood returning lumen 12 and the connector part 2 to allow this catheter main body 1 to communicate with a blood circuit. This connector part 2 has a first chamber 21 which has the base end closed by a first rubber plug 22 having a slit and communicates with the blood supply lumen 11 on the tip and a second chamber 24 which is formed inside this first chamber 21, has the base end closed by a second rubber plug 25 having a slit and communicates with the blood returning lumen 12 on the tip so that the slit 23 of the first rubber plug 22 and the slit 26 of the second rubber plug 25 are coaxially formed.
