PROBLEM TO BE SOLVED: To provide a die head in which the amount of a coating liquid discharged from a slot is uniform in a length direction of a body block, in which neither effort nor expense is necessary for the change of the structure of the flow passage of the coating liquid in the body block even in the case of change of the film thickness and coating speed of the coating liquid coating a material to be coated, and in which a coating test for whether the taper ratio of the structure of a new flow passage is good or not is not required. SOLUTION: In the die head 10 coating the material to be coated with the coating liquid, an internal block 22 constituting a part of a wall 22a dividing the flow passage 20 is installed on the flow passage 20 of the coating liquid in the body block 12. The internal block 22 is designed movably in the flow passage 20. The internal block positioning means 24 adjusting the position of the internal block 22 in the flow passage 20 is installed so that the pressure of the coating liquid flowing in the flow passage 20 may be uniform.
