Provided is a resin sheet using a fluororesin, said resin sheet excelling in a thermal expansion characteristic in the thickness direction. This resin sheet includes the fluororesin and an anisotropic filler, and the anisotropic filler is uniaxially oriented in the film thickness direction and is random in the surface direction. L'invention concerne une feuille de résine utilisant une résine fluorée, ladite feuille de résine présentant une excellente caractéristique de dilatation thermique dans la direction de l'épaisseur. Cette feuille de résine comprend la résine fluorée et une charge anisotrope, et la charge anisotrope est orientée de manière uniaxiale dans la direction de l'épaisseur du film et est aléatoire dans la direction de la surface. フッ素樹脂を用い、厚み方向での熱膨張特性に優れる樹脂シートを提供する。 フッ素樹脂と異方性フィラーとを含んだ樹脂シートで、前記異方性フィラーが膜厚方向に一軸配向し、面方向にはランダムである樹脂シート。
