Zusammenfassung:To provide a method for producing an adhesive sheet having high adhesion between a base material and an adhesive layer in which the base material and the adhesive layer are not peeled off during use and to provide an adhesive sheet.SOLUTION: There is provided a method for producing an adhesive sheet which comprises: a step of applying g a coating liquid containing an organometallic compound onto a surface of a base material 10 to form an organometallic compound layer 21 having a thickness of 0.01 to 1 μm; a step of irradiating the organometallic compound layer 21 with energy to change at least a part of the organometallic compound in the organometallic compound layer 21 into a metal oxide to form a metal oxide layer 20, followed by hydrophilizing treatment; and a step of forming an adhesive layer 30 on the surface of the metal oxide layer 20.SELECTED DRAWING: Figure 1 【課題】基材と粘着層との密着性が高く、使用時に基材と粘着層とが剥離することがない粘着シートの製造方法、及び粘着シートを提供する。【解決手段】基材10の表面上に、有機金属化合物を含む塗布液を塗布して、厚さが0.01~1μmである有機金属化合物層21を形成させる工程と、有機金属化合物層21に、エネルギーを照射することによって、有機金属化合物層21中の有機金属化合物の少なくとも一部を金属酸化物に変化させて金属酸化物層20とし、さらに親水化する工程と、金属酸化物層20の表面上に、粘着層30を形成させる工程と、を含む、粘着シートの製造方法を提供する。【選択図】図1
