PROBLEM TO BE SOLVED: To provide a catheter having cylindrical bodies which are hardly expandable and are easily bent.SOLUTION: A sheath 24 configuring a catheter 10 includes: a first cylindrical body 34 forming the inner peripheral surface of the sheath 24; a second cylindrical body 38 positioned outside the first cylindrical body 34 and forming the outer peripheral surface of the sheath 24; and a complex structure 40 embedded in the wall of the second cylindrical body 38. The complex structure 40 includes: a core material 42 extending along the second cylindrical body 38 and made of a material that is more flexible than the material of the second cylindrical body 38; and a mesh section 44 equipped on the outer peripheral surface of the core material 42 and made of a material that is harder than the material of the second cylindrical body 38. |
