Abstract:
    With a dial for a timepiece comprising a decoration member 21 having a plurality of through holes 22 formed vertically on a luminescent member 10, the cross-sectional area of lower-side holes 24 of the decoration member 21 is formed to be larger than that of upper-side holes 23. Therefore, even if a substrate is thick, the diameter of the upper-side holes 23 of the through holes 22 can be formed to be small sufficiently. Moreover, compared to a dial size 20 for a timepiece wherein the decoration member 21 is placed on the luminescent member 10, the diameter of the through holes 22 of the decoration member 21 is small. Thus, it is possible to take in enough light from the luminescent member 10 through the lower-side holes 24 to ensure the sufficient amount of light through the through holes 22. It is possible to obtain sufficient illuminance for the dial.
