PROBLEM TO BE SOLVED: To reduce the weight, and to improve the strength of a shade panel such as an indoor shade panel of a sunroof for an automobile by manufacturing two aluminum sheets in an integratedly laminating manner by a caulking or brazing method. SOLUTION: This shade panel 1 for an automobile has the two-dimensional or three-dimensional curvature to meet a curved surface of a ceiling part of the automobile in which the panel 1 is installed, an upper plate 3 is laminated on a lower plate 2 in a center portion, and these upper and lower plates 2, 3 are integrated by a caulking or brazing method to form a composite plate. A knob hole 4 to pull out the panel 1 is provided in an upper center. In the figure,○denotes a part to be caulked or brazed. For example, when the sheets are integrated by caulking, a projecting part 5 to be used in the caulking method is provided on the lower plate 2, and a hole 6 corresponding to the projecting part 5 is provided in the upper plate 3, the upper and lower plates 2, 3 overlap by fitting the projecting part 5 to the hole 6, and a top portion of the projecting part projected from the hole 6 is squeezed by a press to form a caulked portion 7.
