PROBLEM TO BE SOLVED: To provide a reinforcing beam structure for an automotive door allowing the improvement in rigidity and reduction in weight and cost. SOLUTION: In this reinforcing beam structure, a reinforcing beam is mounted within a door having a door outer panel partially curved so as to swell to the body outside. Bracket parts 5 and 6 provided on both ends of a pipe part 4 are bonded to the inner surface of a door inner panel to arrange the reinforcing beam 3 in the longitudinal direction of the automotive door, and an extension bracket part 7 extending in the longitudinal direction of the door is provided on at least one of the bracket parts 5 and 6, and adhered to the inner surface of the door outer panel 2.
