Claims6
A resin tube comprising:
- a tubular structure of one or more resin sheets each of which is disposed by being separated by a gap;
- and
- a joint resin sealing at least the gap to seal the tubular structure,
- wherein the joint resin seals the gap, and at least one of an inner circumferential surface and an outer circumferential surface of the tubular structure in a region adjacent the gap,
- wherein the resin sheet is a fiber-reinforced multilayer thermoplastic sheet,
- wherein the fiber-reinforced multilayer thermoplastic sheet is a sheet that includes a reinforcement fiber-containing fabric layer, and a matrix resin sheet laminated to a predetermined thickness,
- wherein the end surfaces of the resin sheet forming end portions of the gap have a fracture surface with a burr, and
- wherein the gap extends in parallel to an axial direction of the resin tube.
