A method for manufacturing a stack, includes forming a first insulation layer on a first support substrate, the first insulation layer including a first thermosetting resin and first inorganic oxide particles; and bonding a first surface of the first insulation layer to a second surface of a second insulation layer including a second thermosetting resin. In this manufacturing method, the second insulation layer includes substantially no inorganic oxide particles or includes second inorganic oxide particles in a content smaller than that of the first inorganic oxide particles included in the first insulation layer.
