Method for manufacturing a tubular body

A method for manufacturing a tubular body, comprising:

• attaching a first band-shaped member to an outer peripheral surface or an inner peripheral surface of at least one end in an axial direction of a cylindrical core, along a circumferential direction of the outer peripheral surface or the inner peripheral surface;
• applying a first film forming resin solution on the outer peripheral surface or the inner peripheral surface of the core, to cover the outer peripheral surface or the inner peripheral surface of the core, and the outer peripheral surface or the inner peripheral surface of at least one end in the width direction of the first band-shaped member that is closer to the center of the core, and to form a coating of the first film forming resin solution;
• drying the coating of the first film forming resin solution to form a first coat film;
• attaching a second band-shaped member to the outer peripheral surface or inner peripheral surface of the end of the first coat film on the side where the first band-shaped member has been attached, such that the end in the width direction of the second band-shaped member that is closer to the center of the core, is closer to the center of the core than the end in the width direction of the first band-shaped member that is closer to the center of the core;
• applying a second film forming resin solution on the outer peripheral surface or the inner peripheral surface of the first coat film, to cover the outer peripheral surface or the inner peripheral surface of the first coat film, and the outer peripheral surface or the inner peripheral surface of at least the end in the width direction of the second band-shaped member that is closer to the center of the core, and to form a coating of the second film forming resin solution;
• drying the coating of the second film forming resin solution to form a second coat film;
• peeling off the first band-shaped member and the second band-shaped member from the core;
• and
• removing the first coat film and the second coat film from the core after the peeling off of the first band-shaped member and the second band-shaped member,
• wherein the first band-shaped member and the second band-shaped member are each attached so that respective superposition sections are formed in which one end in the direction of winding of the first band-shaped member is superimposed with the other end thereof, and one end in the direction of winding of the second band-shaped member is superimposed with the other end thereof, and
• the superposition section of the first band-shaped member and the superposition section of the second band-shaped member do not overlap in the circumferential direction of the core.
