This guide catheter includes a resin tube having an inner lumen through which a guide wire is insertable; a metal pipe attached to an inside of the tube to be coaxial with the tube; and a metal wire having a distal end portion welded to a region more distal than a proximal end of the pipe on an outer circumferential surface of the pipe. The pipe has a most proximal portion formed in a proximal end surface of the pipe, the most proximal portion is more proximal than other portions of the proximal end surface in a central axis direction of the pipe. A welding region of the wire welded to the pipe is formed on the outer circumferential surface of the pipe and a proximal end of the welding region is positioned apart from the most proximal portion of the pipe in the central axis direction of the pipe.
