    Abstract: To provide a cost-effective, stable vacuum insulation panel (10) having at least one lead-through (20) in a main surface (16) of an insulating material supporting body (14) and having a vacuum-tight film envelope (17), it is proposed that the lead-through (20) is formed as a bush (30) with an outer side (32) facing the insulating material supporting body (14) and that on the first bush end (36) is provided a first, preformed collar (37) extending radially away from the bush (30) into the main surface (16) and, opposite said collar, is provided a second collar (39) formed by thermal deformation of the second bush end (38), wherein the vacuum-tight film envelope (17) is welded to the collars (37, 39). A corresponding method for producing the panel is also described.
