The objective of the present invention is to provide a cylindrical structure with which excellent puncture resistance can be imparted while maintaining the flexibility of a base material, by covering the base material using a covering material having excellent flexibility. The present invention provides a cylindrical structure which is provided with a cylindrical base material and a covering material which covers the base material, wherein the covering material includes a copolymer having, as a monomer unit, a polymerizable monomer including a silicone monomer and a fluoroalkyl group.
