A dicing sheet which supports electronic-component aggregation with adhesive in the case of separating the electronic-component aggregation in which a plurality of electronic components are integrated, has a substrate and an adhesion layer which is formed at one surface side of the substrate, in which a concave portion is formed on a surface of the adhesion layer, and the concave portion is formed so that a convex shape member projected from an adhesion surface of the electronic-component aggregation which is adhered to the dicing sheet is inserted. |
