Claim:
An automotive engine hood comprising: an outer panel; and an inner panel; wherein respective edge parts of the outer and the inner panels are joined together such that spaces are formed between the outer and the inner panels; the inner panel has a plurality of ridge-like beads and ridge-like connecting beads connecting at least end parts of the ridge-like beads on one of the opposite sides of the ridge-like beads with respect to length of the ridge-like beads; each of the ridge-like beads has a top wall having a joint surface joined to the outer panel; each of the connecting beads has a top wall having a connecting surface continuous with the joint surfaces of the top walls of the ridge-like beads, and a first inclined surface extending from the connecting surface to a bottom surface surrounded by the adjacent ones of the ridge-like beads and the connecting beads, each of the ridge-like beads has second inclined surfaces adjacent to the first inclined surfaces and extending from opposite side edges of the connecting surface to the bottom surfaces on the opposite sides thereof, an upward concave framing part formed in a framing part of the inner panel surrounding the ridge-like beads and the connecting bead; the spaces extend between the outer and the inner panel in parts corresponding to the upward concave framing part, and in parts corresponding to the bottom surfaces; and distance L between a boundary between the connecting surface and the first inclined surface and a boundary between the first inclined surface and the bottom surface along the surface of the inner panel, and height h of the connecting surface from the bottom surface satisfy an inequality: 1.5 h<L.
