Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a flexible tube that has kink resistance, does not adhere to a sealing bag even when performing sterilization with an autoclave and has a suitable rigidity that is easy to handle. SOLUTION: The flexible tube comprises all of A, B and C as essential components. The component A is a propylene-based random copolymer prepared by copolymerizing propylene and another 2-10C α-olefin under presence of a metallocene catalyst, the content of the other α-olefin being 0.5-8.0 mol%, which satisfies the properties for (1) a melt flow rate at a temperature of 230 deg.C and a load of 21.17 N of 0.1-30 g/10 min, (2) a maximum melting peak temperature of 120 deg.C or higher, and (3) a flexural rigidity of 686 MPa or less. The component B is a styrene copolymer elastomer. The component C is a paraffin oil.
