Abstract

See full text

A film-like epoxy resin composition includes an epoxy resin (A); a curing agent (B); a cure accelerator (C);an inorganic filler (D); and an organic solvent (E). The film-like epoxy resin composition satisfies all the following requirements (1) to (4): (1) at least one of the epoxy resin (A) and the curing agent (B) contains a component being a liquid at 25° C. in an amount of 30% by mass or more based on the total mass of the epoxy resin (A) and the curing agent (B); (2) the content of a volatile portion that volatilizes by being heated at 180° C. for 10 minutes is 0.2% to 1.5% by mass based on the total amount of the epoxy resin composition; (3) the minimum melt viscosity in temperature rising from 40° C. to 200° C. is 800 Pa·s or less; and (4) the film thickness is 50 to 500 μm.
