Abstract

Le problème décrit par la présente invention est de permettre de fournir un modèle ayant une excellente texture et une résistance adéquate. La solution selon l'invention porte sur un espace creux 42 d'une enveloppe translucide 40 qui est rempli d'une charge non transparente, moyennant quoi une partie remplie 30 est formée, et la couleur de la partie remplie 30 est par conséquent visible à travers l'enveloppe 40. Grâce à cette configuration, la partie remplie 30 est visible à travers l'enveloppe translucide 40, et une sensation de transparence et de luxe peut ainsi être produite. En outre, la résistance peut être augmentée par rapport à un cas dans lequel il n'y a pas de partie chargée 30.
