The utility model provides a micro-hole opened vacuum heat-insulation plate. The outer part of the vacuum heat-insulation plate is an air-insulation structural layer, the inner part of the air-insulation structural layer is a vacuum heat-insulation layer, an air absorbing material is arranged between two core layer heat-insulation materials to form the vacuum heat-insulation layer, the core layerheat-insulation materials adopt micro-hole opened polyurethane foam materials, the air-insulation structural layer adopts layers of polyurethane films, and the air absorbing material adopts a reticular glass fiber or felt which is arranged with an air adsorbent. The micro-hole opened vacuum heat-insulation plate increases the contact area between the air absorbing material and the core layer heat-insulation materials; meanwhile, the air absorbent is arranged in a reticular substrate, so that the adding is convenient. The micro-hole opened vacuum heat-insulation plate is suitable for being applied and popularized in mu
