<p>A body (10) of a catheter (1) includes an inner layer (24), a braid (26), and an outer layer (28). The braid (26) includes first and second wires (26a and 26b). The first and second wires (26a and 26b) can be joined together such that the distal end portion (40) of the first wire (26a) winds itself around a side surface of the second wire (26b). A joint (100, 200) includes a first joint portion (110, 210) positioned at the intersection point (30), a second joint portion (120, 220) positioned beyond the first wire (26a) in a width direction (N) of the first wire (26a), and a third joint portion (130, 230) positioned beyond the second wire (26b) in a width direction (N') of the second wire (26b). Thus, even when the first and second wires (26a and 26b) have small thicknesses for size reduction of the braid (26), the first and second wires (26a and 26b) can be joined together with high joint strength by increasing the area of the second joint portion (120, 220) or the thickness of the third joint portion (130, 230).</p> |
