Abstract
A vacuum insulation material includes a plurality of convex protrusions provided on a surface of a core material that is present inside of the bent vacuum insulation material when it is used in a bent state, and so that the core material on which the convex protrusions are provided in advance is inserted into an outer covering material and vacuum-sealed with the outer covering material. By reducing a contact area between the convex protrusions and an inner side surface of the outer covering material in contact with the surface on which the convex protrusions are provided, it is possible to reduce a frictional force between the core material and the outer covering material.
