The utility model relates to a vacuum insulated panel with holes. The heat insulation performance of the vacuum insulated panel is effectively maintained while the holes are formed. The heat sealing technology that one side is flat and the other side is buckled is adopted for the gas insulation structure film, the number of folded edges is reduced, the fold leakage rate is reduced, the edge heat bridge effect is small, the service life of the gas insulation structure film is prolonged, damage to the vacuum heat insulation plate caused by conventional hole opening is avoided, and the gas tightness of the vacuum heat insulation plate is guaranteed. The prefabrication of the perforated core material can also ensure the expected design of the vacuum insulated panel, and the thermal bridge effect caused by conventional trepanning or module splicing is reduced. Compared with the prior art, the trepanned vacuum insulated panel can be used in heat preservation system equipment and other equipment needing trepanning,
