This vehicle body superstructure has a roof side rail (34) that is provided with: a rail flange (61) upon which a roof panel (125) is mounted; a vertical rail wall (64) that hangs down from the outer end (61a) of the rail flange in the vehicle width direction; a bottom rail wall (65) that extends from the lower end (64a) of the vertical rail wall (64) to the outside in the vehicle width direction; and a bulging section (66) formed by allowing the bottom rail wall (65) and the vertical rail wall (64) to bulge toward the center in the vehicle width direction, in order to accommodate a slide rail (51) for a sliding door (21). The outer end (16a) of a roof arch (16) in the vehicle width direction is joined to the bulging section (66). First arch flanges (71, 71) are joined on the lower surface (61b) side of the rail flange (61). Second arch flanges (72, 72) are joined to the lower surface (65b) side of the of the bottom rail wall (65).
