A prepreg winding method according to the present invention includes a step of preparing a plate, a mandrel movable toward and away from the plate, and a press roll movable toward and away from the mandrel and having an axis parallel to the mandrel; a step of mounting a prepreg on the plate, the prepreg being formed by impregnating reinforced fibers with a thermosetting resin sheet; a step of winding a leading end of the prepreg mounted on the plate around the mandrel, and making a pressing force act on the plate and the mandrel therebetween with the prepreg sandwiched between the plate and the mandrel and making a pressing force act on the mandrel and the press roll therebetween with the prepreg sandwiched between the mandrel and the press roll; and a step of winding the prepreg around the mandrel by rotating the mandrel and the press roll by supplying a relative moving force between the plate and the mandrel with the mandrel and the press roll pressed against each other, the relative moving force acting in a direction orthogonal to the axis of the mandrel without intersecting the axis of the mandrel. |
