PROBLEM TO BE SOLVED: To accurately separate liquid flows by setting equal the remaining time of the liquid flows from a liquid introduction inlet to respective liquid separating outlets in a die within an extremely short remaining time and forming a die land and a die lip for equalizing all the liquid outflow amount of respective liquid separating outlets when the liquid flows are separated into two or more. SOLUTION: A liquid is introduced from a liquid introduction inlet 8 and made to flow successively through a manifold 7 expanded laterally on a die land 13 expanded in the die width direction and flowing in parallel with the outlet direction and a die lip 14 as a rectification section, whereon the uniformly expanded liquid flows in the equalized remaining time and the outflow amount from the liquid introduction inlet 8 are made to flow to be equalized in the die width direction, in the above order in the die width direction of a die 6. Then the liquid is separated by liquid partitions 11a-11e and discharged in the respectively equal outflow amount from die liquid separating outlets 12a-12d. A die land clearance 15 of the die lip 14 is microadjusted by a die lip value adjusting bolt 10 to microadjust the outflow amount of respective liquid separating outlets 12a-12d.
