Provided is a sheet forming die capable of finely controlling the flow rates of the respective divided flows of a molten resin with precision. The sheet forming die is a sheet forming die 3 configured to: receive a first molten resin B; to receive a second molten resin A:; and to thus form a sheet-shaped resin-made product by discharging the molten resins A, B from a lip gap 15. The sheet forming die 3 includes: a first passage 17 provided to flow the supplied first molten resin B up to an upstream end of a lip part 23 located upstream of the lip gap 15; a second passage 19 provided to flow the supplied second molten resin A up to the lip part 23, the second passage branching out into a plurality of passageways 19A, 19B in a midstream portion thereof, downstream ends of these passageways 19A, 19B being connected to portions in an upstream end of the lip part 23, respectively; and temperature controller 21 configured to locally control a temperature of a midstream portion of at least one of the passageways 19A, 19B in order to control a flow rate of the second molten resin A in the passageways 19A, 19B.
