Provided is an article that has high scratch resistance and good fingerprint wiping-off property. The article, which has a fine uneven structure containing a cured product of a resin composition on the surface, wherein the push-in elastic modulus (X) [MPa] and creep deformation ratio (Y)[%] of the cured product satisfy the following requirements (1) and (2). 80<=X<=560 (1) Y<=(0.00022X-0.01)×100 (2) L'invention concerne un article qui présente une résistance élevée aux éraflures et une bonne caractéristique de nettoyage des empreintes digitales. Cet article comporte sur sa surface une structure fine irrégulière contenant un produit durci d'une composition de résine, le module élastique à l'enfoncement (X) [MPa] et le rapport de déformation par fluage (Y)[%] du produit durci répondant aux exigences (1) et (2) suivantes : (1) 80<=X<=560, (2) Y<=(0,00022X-0,01)×100.
