ABSTRACT:
A composition containing thermoplastic elastomer and elastic fine particles is extruded into a sheet-like shape from an extruder. Then, by expanding this sheet-like shape member, a covering sheet having minute unevenness attributable to the elastic fine particles formed on the surface is produced. The covering sheet may have an adhesive layer, a substrate layer, a foamed resin layer, etc., on the opposite side to the surface having a matt feeling. Such covering sheet can be produced with good productivity without creating environmental problems such as a problem related to solvent, etc. By molding using the covering sheet, a molding having matt feeling can be obtained.
