A shade structure, comprising: at least one frame, constructed by an upper frame and a lower frame which are parallel to each other, two outer lateral surfaces of the upper frame and the lower frame having two first buckling modules (111, 121) respectively; at least one shading cover, at least comprising: a support layer, having an outer lateral surface; a decorating layer, disposed at the outer lateral surface of the support layer and having one inner lateral surface, stuck on the outer lateral surface of the support layer correspondingly, two upper and lower edges of the decorating layer being reversely bent from the outer lateral surface of the support layer to an inner lateral surface of the support layer, characterized in that the two upper and lower edges of an outer lateral surface of the decorating layer are fastened with a second buckling module via at least one suture, and then the two upper and lower edges of the decorating layer are bent reversely, so as to bend the second buckling module from the outer lateral surface to the inner lateral surface, the suture thus being hidden in the inner lateral surface, and the second buckling module being integrated with the two first buckling modules (111, 121) of the upper frame and the lower frame as a whole. at least one frame, constructed by an upper frame and a lower frame which are parallel to each other, two outer lateral surfaces of the upper frame and the lower frame having two first buckling modules (111, 121) respectively; at least one shading cover, at least comprising: a support layer, having an outer lateral surface; a decorating layer, disposed at the outer lateral surface of the support layer and having one inner lateral surface, stuck on the outer lateral surface of the support layer correspondingly, two upper and lower edges of the decorating layer being reversely bent from the outer lateral surface of the support layer to an inner lateral surface of the support layer, characterized in that the two upper and lower edges of an outer lateral surface of the decorating layer are fastened with a second buckling module via at least one suture, and then the two upper and lower edges of the decorating layer are bent reversely, so as to bend the second buckling module from the outer lateral surface to the inner lateral surface, the suture thus being hidden in the inner lateral surface, and the second buckling module being integrated with the two first buckling modules (111, 121) of the upper frame and the lower frame as a whole. a support layer, having an outer lateral surface; a decorating layer, disposed at the outer lateral surface of the support layer and having one inner lateral surface, stuck on the outer lateral surface of the support layer correspondingly, two upper and lower edges of the decorating layer being reversely bent from the outer lateral surface of the support layer to an inner lateral surface of the support layer, characterized in that the two upper and lower edges of an outer lateral surface of the decorating layer are fastened with a second buckling module via at least one suture, and then the two upper and lower edges of the decorating layer are bent reversely, so as to bend the second buckling module from the outer lateral surface to the inner lateral surface, the suture thus being hidden in the inner lateral surface, and the second buckling module being integrated with the two first buckling modules (111, 121) of the upper frame and the lower frame as a whole.
