Summary:To provide a microstructure forming apparatus capable of continuously forming a microstructure with excellent patterning accuracy along a longitudinal direction of a base film.SOLUTION: A microstructure forming apparatus 100 of the present invention includes: a microstructure forming part 50 that forms a microstructure on a base film 10; and a film transport part 20 that receives the base film 10 on which the microstructure is formed from the microstructure forming part 50 while supplying the base film 10 to the microstructure forming part 50. The microstructure forming part 50 has a first rotating roller 60 and a second rotating roller 70, and the microstructure is formed on a surface of the base film 10 by clamping of the base film 10 by the first rotating roller 60 and the second rotating roller 70 at a position 74 opposite the first rotating roller 60 and the second rotating roller 70. Thereafter, the base film 10 is cooled by cooling means 90 in a front area 73 of the second rotating roller 70 located in front of the opposing position 74 in a conveying direction.SELECTED DRAWING: Figure 1 【課題】基材フィルムの長手方向に沿って、優れたパターニング精度で微細構造を連続的に形成することができる微細構造形成装置を提供すること。【解決手段】本発明の微細構造形成装置100は、基材フィルム10に微細構造を形成する微細構造形成部50と、微細構造形成部50に基材フィルム10を供給しつつ、微細構造が形成された基材フィルム10を微細構造形成部50から受け取るフィルム搬送部20とを備え、微細構造形成部50は、第1回転ローラ60と第2回転ローラ70とを有し、第1回転ローラ60と第2回転ローラ70との対向位置74における、基材フィルム10の第1回転ローラ60と第2回転ローラ70とによる挟持により、基材フィルム10の表面に微細構造が形成され、その後、対向位置74の搬送方向の前方に位置する第2回転ローラ70の前方領域73において、冷却手段90により基材フィルム10が冷却されるよう構成されている。【選択図】図1
