PROBLEM TO BE SOLVED: To provide a die head capable of introducing a coating solution into a slit while uniformly spreading the coating liquid in the longitudinal direction. SOLUTION: The die head is provided with the slit 5 for discharging the coating liquid 2, a flow passage 11 for introducing the coating solution 2 into an opening region of the slit 5, an introducing port 22 for supplying the coating solution 2 to the flow passage 11, and a rotary body 14 rotating around a shaft crossing the discharge direction of the coating solution 2 and along the longitudinal direction of the slit 5 as a rotary shaft, inside the flow passage 11. A blade member 21 arranged in the rotary body 14 and leading the coating solution 2 to both sides of the longitudinal direction of the slit from the introducing port 22 with the rotation of the rotary body 14, is provided.
