Abstract

There is provided a resin sheet containing a filler formed by aggregation of primary particles having a plate shape, a scale shape, or a needle shape, wherein thermal conductivity of the resin sheet can be increased. The resin sheet is characterized in that a ratio (Pi/Po) of a peak area intensity ratio Pi ((002)/(100)) to a peak area intensity ratio Po ((002)/(100)) is 0.13 or more and 0.41 or less, the peak area intensity ratio Pi ((002)/(100)) being a peak area intensity ratio between a (002) plane of the filler and a (100) plane of the filler in the resin sheet, the peak area intensity ratio Pi being obtained by measuring the resin sheet using an In-Plane X-ray diffraction method, the peak area intensity ratio Po ((002)/(100)) being a peak area intensity ratio between the (002) plane of the filler and the (100) plane of the filler in the resin sheet, and the peak area intensity ratio Po being obtained by measuring the resin sheet by an X-ray diffraction method using a focusing method. Alternatively, the resin sheet is characterized in that the peak area intensity ratio Pi ((002)/(100)) is 1.5 or more and 10.0 or less and the peak area intensity ratio Po ((002)/(100)) is 9.0 or more and 13.0 or less.
