A release sheet, on which a stamper receiving layer for producing an optical recording medium is laminated, comprising a release agent layer on a side to which the stamper receiving layer is laminated, wherein the release agent layer is formed using a release agent that contains an organopolysiloxane (other than an MQ resin below) containing an alkenyl group in the molecule, an MQ resin containing an alkenyl group and having, as constituent components, M units represented by formula (1) R12R2—Si—O—  (1) (where, R1 denotes an organic group and R2 denotes an alkenyl group), and Q units represented by formula (2) and a cross-linking agent, and that does not substantially contain particles consisting of inorganic matter, and the alkenyl group content in said MQ resin ranges from 0.5 to 5 wt %. The release sheet can reduce concave defects on a convex-concave pattern transfer surface of the stamper receiving layer. |
