Abstract
An exterior material may be configured to form an exterior of a home appliance, the exterior material includes a base material having a hierarchical circular structure pattern on the surface. The hierarchical circular structure pattern may include a plurality of circular structures having diameters different from each other, and a pattern density may be, in percentage of area of the surface, about 20 to 90%.
