Abstract
A catheter is capable of firmly fixing a shaft and a hub, and preventing a decrease in dimensional accuracy of an outer side of the hub in a radial direction. The catheter includes: a shaft that is a tubular body in which a lumen extending the shaft from a distal end to a proximal end is formed, and that includes a shaft proximal surface in which the lumen is opened and a shaft outer surface that is an outer peripheral surface of the tubular body; and a hub that is attached to the proximal end of the shaft. The hub includes a tubular accommodation unit configured to accommodate the shaft, the accommodation unit includes a hub melted surface that is directly welded to the shaft outer surface, and an absolute value of a residual strain of the accommodation unit decreases outward in a radial direction from the hub melted surface.
