Zusammenfassung:	Disclosed are a vacuum suction nozzle for improving vacuum suction performance and a vacuum suction apparatus including the same. The nozzle includes blade portions extending from both sides thereof so as to reduce a gap occurring between the nozzle and an outer skin material for a vacuum insulation panel (VIP) or other vacuum wrapping paper when the outer skin material or vacuum wrapping paper is sealed, thereby minimizing the occurrence of a leak and thus enabling efficient vacuum suction. Further, the nozzle achieves efficient vacuum suctioning by ensuring a suction channel inside the vacuum insulation panel (VIP) or other vacuum wrapping paper through a protrusion extending to the front of the nozzle.
