The medical stent includes: a coil (3) formed by winding a wire (2) around a given axis (C1); an outer layer (4) formed in an approximately tubular shape with a first resin material, and provided on an outer circumference side of so as to be the coil coaxially with the coil; an inner layer (5) formed in an approximately tubular shape and provided in an inner circumference side of the coil coaxially with the coil; and an elastic member (6) formed of a second resin material, which is different from the first resin material, and formed such that a surface-treated section (6b), which is formed on an outer circumferential surface of one end side, is fixed with the surface-treated section brought into contact with the outer circumferential surface of one end (6a) side and the other end (6c) formed to extend to the central portion side of the outer layer along the axis and also to open to an outside in the radial direction of the outer layer. A melting temperature of the second resin material is higher than a melting temperature of the first resin material, and the surface-treated section of the elastic member and the outer circumferential surface of the outer layer are connected to each other at a temperature equal to or higher than the melting temperature of the first resin material and lower than the melting temperature of the second resin material. |
