Tubular body

A tubular body, comprising:

• a plurality of first wires distributed in an annular portion of the tubular body;
• and
• a plurality of deformed second wires alternately disposed between each of the plurality of first wires, the plurality of first wires and the plurality of deformed second wires being in an alternately twisted arrangement in a longitudinal direction of the tubular body, wherein
• each of the plurality of first wires has a substantially circular shape in a cross section view with respect to the longitudinal direction of the tubular body,
• each of the plurality of deformed second wires has a non-circular shape in the cross section view, has an arcuate side portion that receive a part of a side surface of an adjacent wire of the plurality of first wires, has an annular sector shape protruding in a radial direction in the cross section view of the tubular body, and is configured by twisting a plurality of third wires to form the non-circular shape having the arcuate side portion and the annular sector shape, and
• each of the plurality of third wires has an arch shape protruding in a radial direction in the cross section view of the tubular body.
