PROBLEM TO BE SOLVED: To provide a ceramic product provided with decoration which has high brightness of a surface independently of painting using a pigment and changes the color tone of the surface according to light to be irradiated with and the observation angle.SOLUTION: A ceramic product 1 includes a multilayer film 31 which is composed of a plurality of types of layers 3a and 3b made of inorganic dielectrics of different refractive indices and laminated repeatedly on the surface of a ceramic substrate 2 and a protective film 32 which covers the multilayer film 31 and is made of a metal or an inorganic compound. The multilayer film 31 is preferably vapor-deposited on the surface of the ceramic substrate 2.
【課題】顔料を用いた絵付けによらず、表面が高い輝度を有し、かつ照射する光や観察する角度に応じて、表面が異なる色調に見えるような装飾を施されたセラミック製品を提供すること。【解決手段】セラミック製品1は、セラミック基材2の表面に、屈折率の異なる無機誘電体よりなる複数種の層3a,3bが繰り返して積層された多層膜31と、多層膜31の表面を被覆する金属または無機化合物よりなる保護膜32と、を有する。多層膜31は、セラミック基材2の表面に蒸着されていることが望ましい。【選択図】図1
