A cyclic-olefin-based thermoplastic resin for thermal imprint to be used in the production of a sheet or a film which contains at least one of skeletons represented by the following chemical equation 1 or the following chemical equation 2 in a main chain. The glass transition temperature Tg (&#xb0; C.) and the value ([M]) of MFR at 260&#xb0; C. satisfy the following equation 1, and [M]&#x3c;30. The thermal imprint characteristics (transferability, mold release characteristic, and the like) are superior and the productivity (throughput) is improved.

The present invention provides an imprinting device and an imprinting method which can uniformly apply pressure between a mold and a molding object and which can increase and decrease a temperature at a fast speed. An imprinting device is for transferring a pattern on a mold to a film molding object and comprises a stage for holding the mold, a pressurizing-chamber casing which configures a pressurizing-chamber together with the molding object, sealing means which airtightly seals a space between the pressurizing-chamber casing and the molding object, opening and closing means which opens and closes the space between the pressurizing-chamber casing and the molding object, pressurizing means which adjusts atmospheric pressure in the pressurizing-chamber, heating means which heats either one of or both of the mold and the molding object, and degassing means which eliminates any gas present between the mold and the molding object.
