A serving tray includes a holding portion, and handles at two sides of the holding portion; the holding portion has trenches formed on an upper side, recesses formed on a bottom, a through hole, upper flow passages formed on the upper side, and lower flow passages formed on the bottom; the handles have second recesses formed thereon. Slip-prevention rubber sheets are attached to the trenches and the recesses by means of injecting melted rubber into a mold used for making the holding portion and the handles via the through hole for the melted rubber to be applied over the trenches, and the recesses via the upper and the lower flow passages.
