Abstract
With a dial for a timepiece comprising a decoration member having a plurality of through holes formed vertically on a luminescent member , the cross-sectional area of lower-side holes of the decoration member is formed to be larger than that of upper-side holes . Therefore, even if a substrate is thick, the diameter of the upper-side holes of the through holes can be formed to be small sufficiently. Moreover, compared to a dial size for a timepiece wherein the decoration member is placed on the luminescent member , the diameter of the through holes of the decoration member is small. Thus, it is possible to take in enough light from the luminescent member through the lower-side holes to ensure the sufficient amount of light through the through holes . It is possible to obtain sufficient illuminance for the dial.
