Abrégé
It is an object of the present invention to provide a feed block that can stably produce a resin sheet in which a main material and an auxiliary material are stacked on top of another. The feed block feeds laminated molten resin P to a die, wherein laminated molten resin P has at least one main material A that consists of a molten resin in a shape of a plate or a sheet and auxiliary material B that consists of a molten resin in a shape of a plate or a sheet, wherein auxiliary material B is stacked on at least a part of at least one main material A with regard to a width direction thereof. The feed block has: at least one main material forming channel 17, 18 that allows a molten resin to flow therethrough in order to form main material A into a shape of a plate or a sheet; auxiliary material forming channel 19 that allows a molten resin to flow therethrough in order to form auxiliary material B into a shape of a plate or a sheet; merging section 23 that forms laminated molten resin P, wherein at least one main material forming channel17, 18 and auxiliary material forming channel 19 merge at merging section 23; and channel 24 for laminated molten resin P that is located downstream of merging section 23 and that feeds laminated molten resin P to the die.
