Abstract
A thermosetting resin sheet includes a prepreg layer and a resin sheet layer stacked on the prepreg layer. The prepreg layer includes a base member and an uncured product or semi-cured product of a first thermosetting resin composition impregnated into the base member. The resin sheet layer is an uncured product or semi-cured product of a second thermosetting resin composition. A curing time of the resin sheet layer is longer than a curing time of the prepreg layer.
