PROBLEM TO BE SOLVED: To provide the die of an extruder capable of obtaining a uniform strand even if the flow channel length of a discharge orifice is different from that of another discharge orifice. SOLUTION: In the die 40 of the extruder having a plurality of discharge orifices 51 and 55 for discharging a molten resin in a strand like state and characterized in that the flow channel length of one discharge orifice is different from that of another discharge orifice, the standard deviation of the pressure loss of all of the discharge orifices is set to 15 or below.
