PROBLEM TO BE SOLVED: To provide an epoxy resin/inorganic matter composite sheet for sealing that has good workability, achieves the reduction in both a coefficient of linear expansion and a flexural modulus after cured to inhibit warpage, has excellent laser processability and has high sealing reliability.SOLUTION: The epoxy resin/inorganic matter composite sheet for sealing is formed in a semi-cured state by applying an epoxy resin composition comprising as essential components an epoxy resin, a curing agent and an inorganic filler to a surface of a carrier material and heating/drying the composition. A cured product of the epoxy resin/inorganic matter composite sheet for sealing has a glass transition temperature of less than 50°C and has a coefficient of linear expansion at a temperature lower than the glass transition temperature of not less than 5 ppm/°C to less than 20 ppm/°C. |
