PROBLEM TO BE SOLVED: To provide a curved tubular body made inexpensive while ensuring strength in a curved part. SOLUTION: The curved tubular body is constituted so that at least a hard rod-like body 2, which is curved so as to closely come into contact with the inner peripheral surface of the curved part 11, is built in the curved part 11 and molded by overlaying the plastically deformable hard rod-like body 2 with a prepreg made of a fiber reinforced resin on so as to wind the prepreg around the hard rod-like body 2 and curving the region to be curved of the whole into a predetermined curvature before baking the prepreg.
