PROBLEM TO BE SOLVED: To provide adhesive sheets for graphite sheets that have excellent appearances and allow defects and the like to be detected with improved accuracy.SOLUTION: An adhesive sheet 1 has base material 10, and an adhesive layer 20 provided on one surface 10A of the base material. The adhesive sheet 1 is of a one-side adhesive type and is used by stuck on a graphite sheet, with the base material 10 having a black layer 14. The adhesive sheet 1 has a light transmittance of 12-30%, and the adhesive sheet rear face 1B has a 60° gloss value of 10 or less.SELECTED DRAWING: Figure 1 【課題】優れた外観を有し、欠陥等の検出精度が向上したグラファイトシート用粘着シート。【解決手段】粘着シート１は基材１０と、基材の一方の表面１０Ａに設けられた粘着剤層２０とを備え，基材１０は黒色層１４を含むグラファイトシートに貼り付けて用いられる片面接着性の粘着シート１。粘着シート１の光透過率は１２〜３０％、粘着シート背面１Ｂの６０°グロス値は１０以下である粘着シート１。【選択図】図１
