Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an adhesive sheet having excellent foaming resistance.SOLUTION: This invention relates to an adhesive sheet. When an adhesion of the adhesive sheet when peeled off from a polycarbonate substrate at the rate of 300 mm/min in 180° direction is defined as R, and an adhesion of the adhesive sheet when peeled off from the polycarbonate substrate at the rate of 20 mm/min in 180° direction is defined as S, a value represented by S/R is 1 or more.SELECTED DRAWING: None 【課題】本発明は、優れた耐発泡性を有する粘着シートを提供することを課題とする。【解決手段】本発明は、１８０°方向に３００ｍｍ／ｍｉｎの速度でポリカーボネート基材から剥離した時の粘着力をＲとし、１８０°方向に２０ｍｍ／ｍｉｎの速度でポリカーボネート基材から剥離した時の粘着力をＳとした場合、Ｓ／Ｒで表される値が１以上である粘着シートに関する。【選択図】なし
