PROBLEM TO BE SOLVED: To provide a flexible pole which, even when receiving impact, is hardly broken in comparison with conventionally used poles.SOLUTION: A flexible pole has a structure laminating a first cylindrical body 3A located on the outer peripheral side and a second cylindrical body 3B located on the inner peripheral side. The first cylindrical body 3A located on the outer peripheral side is a cylindrical body made of polyurethane. The first cylindrical body 3A may be made of a synthetic resin other than polyurethane. The second cylindrical body 3B located on the inner peripheral side is composed of a cylindrical resin impregnated molding which is formed by impregnating a non-woven cloth 3D with a liquid urethane resin raw material composition and, in this state, polymerizing components in the urethane resin raw material composition. The second cylindrical body 3B may be produced by impregnating the non-woven cloth 3D with a liquid resin composition other than the urethane resin raw material composition. |
