Zusammenfassung:	To provide a heat conductive sheet that has high heat conductivity and strong adhesive strength, and does not deteriorate in heat conductivity and adhesive strength even when stored under high temperature and high humidity.SOLUTION: Provided is a heat conductive sheet containing at least zinc oxide and acrylic adhesive, in which the arithmetic mean particle size of the zinc oxide is 8 μm or more and the acid value of the acrylic adhesive is 2 mgKOH/g or less, the heat conductive sheet further containing a particular acidic phosphoric acid ester compound.SELECTED DRAWING: None 【課題】高い熱伝導性を有し、粘着力が強く、高温高湿下で保管しても熱伝導性や粘着力の劣化のない熱伝導性シートを提供する。【解決手段】少なくとも酸化亜鉛とアクリル粘着剤を含有する熱伝導性シートを有する熱伝導性シートであって、該酸化亜鉛の算術平均粒子径が８μｍ以上、該アクリル粘着剤の酸価が２ｍｇＫＯＨ／ｇ以下であり、更に該熱伝導性シートが特定の酸性リン酸エステル化合物を含有することを特徴とする熱伝導性シート。【選択図】なし
