Zusammenfassung:To provide a novel fluororesin sheet and fluororesin adhesive tape having an unconventionally high degree of freedom in use development.SOLUTION: A fluororesin sheet is mainly composed of a fluororesin with a blackness represented by an L* value of an L*a*b* colorimetric system is 30 or less and a surface resistivity of 1×1010 Ω/sq or more; or a fluororesin sheet is mainly composed of a fluororesin and includes a complex oxide based black filler. An adhesive tape includes a base material sheet and an adhesive layer provided on one face of the base material sheet, in which the base material sheet is one of the fluororesin sheets.SELECTED DRAWING: Figure 1 【課題】従来になく用途展開の自由度が高い、新規なフッ素樹脂シート及びフッ素樹脂粘着テープを提供する。【解決手段】主としてフッ素樹脂から構成され、L*a*b*表色系のL*値により表した黒色度が30以下であり、表面抵抗率が1×1010Ω/sq以上であるフッ素樹脂シート;又は、主としてフッ素樹脂から構成され、複合酸化物系の黒色フィラーを含有するフッ素樹脂シート;とする。また、基材シートと、基材シートの一方の面に設けられた粘着剤層と、を含み、基材シートが上記いずれかのフッ素樹脂シートである粘着テープとする。【選択図】図1
