Abstract: The invention provides a holder for a polished work in which the warpage suppression or plate thickness accuracy of the holder for a polished work is improved, the generation of scratches in a polished work is suppressed so as to improve the abrasion resistance, and furthermore, economic advantages are provided. The holder for a polished work of the invention includes a first resin layer produced by impregnating a first resin composition into a first fiber base material, and heating and pressurizing the first fiber base material as an outermost layer, the first fiber base material is a glass fiber base material, and a structure derived from a resin having a novolac skeleton is included in a proportion of 50 mass % or more in the first resin layer excluding the first fiber base material.
