<p><P>PROBLEM TO BE SOLVED: To provide a ceramic member having a visible surface and which is intended so as to be attached on a timepiece case. <P>SOLUTION: The visible surface (1a) includes holes (2) for each feature. The holes (2) have characteristic shapes, in which each depth is equal to at least 0.05 mm, in which a sidewall (2a) of each hole is substantially perpendicular to the visible surface, and in which the bottom part of each hole (2) includes a first bonding layer (3) of Ti, Ta, Cr, or Th types, having a thickness of at least 100 nm and at least a single second layer, consisting of a group of Au, Ag, CrN, Ni, Pt, TiN, ZrN, Pd, or an alloy thereof, having a thickness of at least 100 nm. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
