The utility model relates to the getter device of a vacuum thermal insulation plate and comprises a container and a getter that is positioned in the container. The getter comprises desiccant, barium lithium alloy and cobalt oxide. The utility model is characterized in that: the container is thin slice shaped and mesh shaped rice paper packaging bag whose aperture of the mesh is smaller than the dimension of the desiccant grain. The utility model is made into thin slice shape and adopts rice paper that is with excellent ventilation property and mesh as the packaging bag, thus the contact area between the desiccant and the core layer is large so as to improve the vent effect. When installing the getter device into the vacuum heat insulating plate, spread the getter device between the upper and the lower plate of the fiber glass core layer of the vacuum insulating plate. Place the getter on one side of the foaming plate or split the foaming plate for better utilization of the getter, if the vacuum heat insulatin
