A hot-press sheet (20) comprises a sheet-shaped base material (1) and a release coating film (2) applied to a surface of the base material (1), in which the coating film (2) completely covers an entire surface of the base material (1) to provide air-tightness for the hot-press sheet (20). The coating film (2) comprises a resin composition as a host material, and 5% or more by weight of organic powder and 5% or more by weight of inorganic powder are mixed in 100% by weight of the resin composition which forms the coating film (2), so that the mixture of 5 to 55% by weight of the organic powder and 5 to 55% by weight of the inorganic powder becomes 30 to 60% by weight in total.
