A stiffening structure for an automotive door panel part according to the present invention includes a door outer panelmade of a metal sheet curved along a height direction, and in which a character lineis formed; and an impact beamdisposed at an inner surface side of the door outer panel. The stiffening structure improves tensile rigidity of the door outer panelby attaching a stiffening membermade of resin to the inner surface of the door outer panel. The stiffening memberincludes vertical bone portionsextending in a streak shape from the impact beamto the character linealong a curve of the door outer panel. The vertical bone portionsare arranged at a predetermined interval in a front-rear direction of the door outer panel, and outer surface of the vertical bone portionsis bonded to the inner surface of the door outer panel
