Abstract of the Disclosure A balloon catheter is provided, which comprises a catheter body made of a flexible tube provided with at least one inner channel and with an annular groove formed on an outer surfact near the distal end portion of the tube, and a balloon covering the annular groove in such a manner that the outer diameter of the balloon is equal to or smaller than a maximum diameter of the distal end portion of the tube, the balloon being expanded or shrunk through another inner channel. A method of manufacturing the balloon catheter which comprises the steps of reducing an outer diameter of a distal end portion of the catheter body while keeping a desired inner channel undamaged, mounting a tubular heat-resistant member to a prospective balloon mounting portion of the reduced diameter portion, molding a reduced diameter portion extruded from the heat- resistant member into a spherical shape, and mounting an inflatable balloon to the balloon mounting portion after removing the heat-resistant member.
