A body of a catheter includes an inner layer, a braid, and an outer layer. The braid includes first and second wires. The first and second wires can be joined together such that the distal end portion of the first wire winds itself around a side surface of the second wire. A joint includes a first joint portion positioned at the intersection point, a second joint portion positioned beyond the first wire in a width direction of the first wire, and a third joint portion positioned beyond the second wire in a width direction of the second wire. Thus, even when the first and second wires have small thicknesses for size reduction of the braid, the first and second wires can be joined together with high joint strength by increasing the area of the second joint portion or the thickness of the third joint portion.
