Zusammenfassung:	To provide a foamable adhesive sheet that offers improved adhesive strength, a method for producing a foamable adhesive sheet, a method for producing an article, and a method for testing the quality of a foamable adhesive sheet.SOLUTION: A foamable adhesive sheet includes an adhesive layer. The adhesive layer includes a thermosetting adhesive and a foamer. The foamer includes thermally expandable microcapsules. Using thermomechanical analysis, when a compressive load is applied, the temperature is increased at a predetermined rate, and the displacement is measured, the maximum extrapolated displacement temperature is at least -35°C below and at most -10°C below the maximum foaming temperature of the foamer.SELECTED DRAWING: Figure 1 【課題】接着強度を向上させることが可能な発泡性接着シート、発泡性接着シートの製造方法、物品の製造方法、および発泡性接着シートの品質検査方法を提供する。【解決手段】本開示は、接着層を有する発泡性接着シートであって、上記接着層が、熱硬化性の接着剤と、発泡剤とを含有し、上記発泡剤が、熱膨張性マイクロカプセルであり、熱機械分析により、圧縮荷重を加えて、所定の昇温速度で昇温し、変位を測定したときの、最大変位外挿温度が、上記発泡剤の最大発泡温度－３５℃以上、上記発泡剤の最大発泡温度－１０℃以下である、発泡性接着シートを提供する。【選択図】図１
