PROBLEM TO BE SOLVED: To provide a die head which is capable of accurately making the gap size of the slit gap constant to the die head longitudinal direction while using a first and second die blocks which are thinly weight-reduced. SOLUTION: In the die head 13 having a structure to clamp the first and second die blocks 17, 18 with a plurality of bolts 22, the die head is characterized in that mating faces 17b, 18b for butting both the die blocks 17, 18 each other are enlarged and the distance from the mating face to the leading front of the slit gap 19 are shortened by forming the manifold 20 to be formed to one of the die block 18 inside the die block 18 and in that the gap size d of the slit gap 19 becomes constant to the die head longitudinal direction by suppressing the deflection of the die blocks 17, 18 produced by clamping the bolt small.
