Abstract The present invention relates to a capillary pipe for refrigerator/air conditioner. The capillary pipe comprises a contracted part which formed on the capillary tube and has a smaller diameter than it and has a plurality of supporting ribs which are integratedly formed on the outer circumferential surface of the contracted part in the longitudinal direction of the capillary pipe. Thus, the rigidity is improved in forming the contracted part on the capillary pipe and it prevents cracking generated in forming the contracted part and improves the reliability of a product. The present invention also relates to the manufacturing method of this capillary pipe.
