There are provided an accessory member capable of suppression of adhesion of dirt to its surface, and easy removal of adherent dirt, as well as to provide an accessory comprising the accessory member. An accessory member includes a sintered ceramic body, a kurtosis Rku derived from a surface roughness curve of an outer surface of the sintered ceramic body falling in a range of 0.5 or more and 2.5 or less. In this case, since the sintered ceramic body has many rounded asperities at its outer surface, it is possible to suppress adhesion of dirt to the outer surface, as well as to remove adherent dirt with ease. |
