Summary:PROBLEM TO BE SOLVED: To provide a window unit having excellent durability in the case where flying objects (chips, for example) which could be generated during machining by a machine tool collide on the unit.SOLUTION: A window unit 1 is installed to a machining center 10, and used for viewing a processing region S1 of the machining center 10 in that state, or taking light into the processing region S1. The window unit 1 comprises: a plate member 21 composed of polycarbonate-based resin; a transparent first substrate 2a having a hard coat layer 22 formed on one surface side of the plate member 21; and a transparent second substrate 2b arranged in a facing manner to the first substrate 2a via a middle layer 5. 【課題】工作機械による機械加工時に生じ得る飛翔物（例えば切りくず等）が衝突した場合の耐久性に優れた窓ユニットを提供すること。【解決手段】窓ユニット１は、マシニングセンタ１０に装着され、その状態でマシニングセンタ１０での加工領域Ｓ１を視認したり、加工領域Ｓ１に光を採り込んだりするの用いられるものである。この窓ユニット１は、ポリカーボネート系樹脂で構成された板部材２１と、板部材２１の片面側に形成されたハードコート層２２とを有する透明な第１の基板２ａと、第１の基板２ａに対し中間層５を介して対向配置された透明な第２の基板２ｂとを備える。【選択図】図２
