Zusammenfassung:	To provide a pressure sensitive adhesive sheet excellent in infrared-ray interception properties.SOLUTION: A pressure sensitive adhesive sheet 1 includes adhesive layers 21 and 22. The pressure sensitive adhesive sheet has light transmittance of 5% or less in a thickness direction of a wavelength region of 780 to 2500 nm. Further, the pressure sensitive adhesive sheet has light transmittance of 0.01% or less in a sheet plane direction in a wavelength region of 380 to 2500 nm. Preferably, the pressure sensitive adhesive sheet includes a substrate layer 10 supporting the adhesive layer, and the substrate layer is composed of a resin film containing a black colorant.SELECTED DRAWING: Figure 1 【課題】赤外線遮断性に優れる粘着シートを提供する。【解決手段】粘着剤層２１、２２を備える粘着シート１が提供される。この粘着シートは、波長域７８０〜２５００ｎｍの厚さ方向光線透過率が５％以下である。また、粘着シートは、波長域３８０〜２５００ｎｍのシート面方向光線透過率が０．０１％以下である。好ましくは、前記粘着剤層を支持する基材層１０を備えており、該基材層は、黒色着色剤を含有する樹脂フィルムからなる。【選択図】図１
