In an automobile hood 1, an outer panel 3 and an inner panel 2 are joined together by a plurality of spot-shaped joints 20. The automobile hood 1 has a first-direction joint row 30 in which a plurality of the joints 20 are arranged at an interval from each other in a cross direction X, and a second-direction joint row 40 in which a plurality of the joints 20 are arranged at an interval from each other in a longitudinal direction Y that is perpendicular to the cross direction X. A curvature 1/R1 in a direction along the first-direction joint row 30 in a region of the outer panel 3 corresponding to the first-direction joint row 30 is smaller than a curvature 1/R2 in a direction along the second-direction joint row 40 in a region of the outer panel 3 corresponding to the second-direction joint row 40. An interval X1 between the joints 20 in the first-direction joint row 30 is greater than an interval Y2 between the joints 20 in the second-direction joint row 40.
