PROBLEM TO BE SOLVED: To provide a die head for coating capable of carrying out high precision coating. SOLUTION: In the die head for coating 12 for discharging a coating liquid while moving relative to a base material 1 and applying the coating liquid to the surface of the base material 1, the high precision coating is performed by providing a surface layer 13 having poor wettability to the coating liquid on a tip end side surface 12c to make the contact angle with the coating liquid larger than that of a lip part 12b with the coating liquid to prevent the instability caused by the spreading of a bead 3 to the tip end side surface 12c in the coating and preventing stripes or step nonuniformity which tend to occur on a coating layer 4.
