PROBLEM TO BE SOLVED: To prevent the penetration of a resin in the gap between the width control surface of an inner deckle and a lip part or the leak of the resin from the gap. SOLUTION: In this T-die for extrusion molding constituted so that the inner deckle 5 is interpolated on both sides in the width direction of the lip part 6 from the manifold part formed to a die body 1 to the outlet 6b of the lip part 6 to adjust the width of a sheetlike molded product and a plurality of lip interval adjusting tools 21 for adjusting the thickness of the sheetlike molded product is arranged to the die body 1, the interval adjusting tools 21 are made movable so as to be freely adjusted positionally in the width direction of the lip part 6. When the position of the inner deckle 5 is adjusted, the movable interval adjusting tools 21 are positionally adjusted in the vicinity of the inner surface 5a of the inner deckle 5 to press the lip part 6 and the lip part 6 is brought into close contact with the inner deckle 5 in the vicinity of the inner surface 5a thereof.
