Provided are a sealing composite that can be easily formed into a sheet, and a sealing sheet obtained from said sealing composite, said sheet having excellent adhesion to devices, upon thermocompression bonding, and also having low moisture permeability and excellent heat resistance after curing. The sealing composite contains: (A) a bisphenol epoxy resin having weight-average molecular weight between 3×103 and 1×104; (B) a phenol epoxy resin having weight-average molecular weight between 200 and 800; (C) a hardening accelerator; and (D) a silane coupling agent having an epoxy group or a functional group that can react with epoxy groups. By weight, the sealing composite contains 100 to 2000 parts of component (A) for each 100 parts of components (B), (C), and (D) combined. |
