A vehicular door frame includes an outer member constituting a glass-run housing portion and an inner member to be coupled to the outer member. The outer member includes a folded portion with substantially U-shaped cross-section and a return portion. The return portion raises a portion of the housing portion closer to a proximal end portion than the folded portion in a flat manner at least to a first-side end position of the folded portion. The inner member includes an extended portion and a distal end surface on an edge portion of the extended portion. A projection portion on the distal end surface protrudes toward a first side. The projection portion is arranged at a predetermined position on the inner member in the longitudinal direction, and is heated and melted through current concentration during resistance welding, and the distal end surface and a facing portion of the folded portion are pressure-bonded.
