A liquid resin composition for sealing contains an epoxy resin (A); a curing agent (B) containing at least one amino group in a molecule; a polymer resin (C); and an inorganic filler (D), wherein the polymer resin (C) has a weight average molecular weight of 10,000 or more.

Liquid resin composition for sealing and electronic component device

A sealing resin composition contains an epoxy resin (A), a curing agent (B) having at least one amino group in one molecule, and an inorganic filler (C), wherein the inorganic filler (C) contains a first inorganic filler (C1) having an average particle size from 0.1 μm to 20 μm and a second inorganic filler (C2) having an average particle size from 10 nm to 80 nm, and a value obtained by multiplying a specific surface area of the inorganic filler (C), by a proportion of a mass of the inorganic filler (C) in a solid mass of the sealing resin composition, is 4.0 m/g or more.
