Abstract: A balloon catheter includes a shaft inserted into a body; a balloon attached to the shaft on a distal end side and is expandable by an expansion fluid supplied from a side of a proximal end of the shaft; an elastic band wound around an outer periphery of an intermediate portion between a distal end portion and a proximal end portion of the balloon , and is configured to limit expansion of the balloon at the intermediate portion; and a covering member covering an outer periphery of the elastic band. The balloon is expandable to a maximum expansion diameter from a folded state, in accordance with pressure of the expansion fluid, the elastic band is expandable beyond the secured diameter, by being elastically deformed by the balloon expanding, and the covering member is expandable by being elastically deformed by the balloon or the elastic band expanding.
