1. A sheet for heat bonding in semiconductor manufacturing, the sheet comprising:
a pre-sintering layer; and
an adhesive layer containing at least an organic binder and metal fine particles, wherein
the pre-sintering layer and the adhesive layer are directly in contact with each other;
the pre-sintering layer contains an organic binder;
the organic binder contained in the pre-sintering layer contains a thermally decomposable binder;
the thermally decomposable binder contained in the pre-sintering layer comprises at least one of polycarbonate, acrylic resin, ethyl cellulose, or polyvinyl alcohol;
the organic binder contained in the adhesive layer contains polycarbonate; and
a content of the metal fine particles contained in the adhesive layer is 10% or more and 30% or less by volume based on the entire adhesive layer.
