Timepiece component, timepiece movement, and timepiece

Abstract

A timepiece component includes a base material including silicon as a main component, and a light reflecting layer formed on the base material and including a first silicon oxide layer, a silicon layer, and a second silicon oxide layer stacked in this order, when the light reflecting layer is viewed in plan view, the light reflecting layer includes a first region and a second region, and at least one of the thicknesses of the first silicon oxide layer in the first region and the second region and the thicknesses of the second silicon oxide layer in the first region and the second region is set such that the thicknesses are different from each other.
