A transfer apparatus includes a rolled web mold installation part for installing a rolled web mold around which the mold is wound, a transfer roller for winding the mold fed out from the rolled web mold, a winding roll for winding up the mold, a winding roll installation part for installing the winding roll therein, and a mold installation assisting part for guiding the mold fed out from the rolled web mold up to the winding roll while suppressing an occurrence of wrinkles in the mold fed out from the rolled web mold.

A method for producing a plastic element provided with fine surface roughness is provided. In the method, etching of a surface of the plastic element is performed separately in a first step and in a second step, in the first step, fine roughness having a predetermined average value of pitch in the range from 0.05 to 1 micrometer is generated on the surface through reactive ion etching in an atmosphere of a first gas; and in the second step, an average value of depth of the fine roughness generated in the first step is adjusted to a predetermined value in the range from 0.15 to 1.5 micrometers while the predetermined average value of pitch is substantially maintained through reactive ion etching in an atmosphere of a second gas, reactivity to the plastic element of the second gas being lower than reactivity to the plastic element of the first gas.

The present invention provides a scaffold for tissue regeneration and a method of manufacturing the same. The scaffold for tissue regeneration of the present invention includes grooves and ridges formed on one surface thereof, wherein the grooves or ridges have a plurality of nanopores formed thereon, thereby providing an environment suitable for attachment, differentiation, growth, and migration of cells. Therefore, the scaffold may be effectively used as a material for tissue regeneration.

An antenna conductor is cooled to stably generate plasma, and unexpected fluctuation in the electrostatic capacity of a variable capacitor connected to the antenna conductor is suppressed while cooling the variable capacitor. A plasma processing device which generates plasma in a vacuum container and processes a substrate by using the plasma is provided. The plasma processing device includes: an antenna conductor through which a high-frequency current is caused to flow to generate plasma, and a variable capacitor which is electrically connected to the antenna conductor. The antenna conductor has a flow path in which a cooling liquid flows. A dielectric of the variable capacitor is constituted of the cooling liquid flowing through the antenna conductor.
