A rectifying diode package structure includes a base which has a holding deck to hold a diode chip and a protective portion on the perimeter of the base to form sealing space filled by a filling material to seal the diode chip in an integrated manner. The diode chip has a conductive element extended outside the sealing space. The holding deck and the protective portion are interposed by a buffer ring embedded in the filling material. The buffer ring has at least one retaining ridge which has at least one first end and one second end of different cross sections formed in an upright manner to form a retaining relationship between the buffer ring and the filling material.
