摘要

The present invention is characterized in that the blocking cylinder (11) comprises a tubular blocking layer (11a) made of a barrier material, a blocking layer (11a) disposed in contact with at least the inner circumferential surface of the blocking layer (11a) And a cylindrical coating layer (11 b). One end portion of the covering layer (11 b) protrudes to the outside more than the end portion of the blocking layer (11 a) arranged on the outer peripheral side. The blocking cylinder (11) has an inner peripheral surface of the coating layer (11 b) forming the inner surface of the discharge hole (5) and an end surface on the one end side in the axial direction of the coating layer (11 b) ) Of the blocking layer (11a) protruding from the axial end portion are embedded in the base material resin in contact with the base material resin.
