PROBLEM TO BE SOLVED: To provide an adhesives composition, free from any halogen compound and other materials giving load to environment, that is excellent in storability in a semi-cured state and is excellent in adhesiveness, heat resistance, migration resistance, and flame resistance in a cured state, and to provide an adhesive sheet and coverlay film using the composition. SOLUTION: The adhesive composition includes (A) a non-halogen-based epoxy resin, (B) a synthetic rubber, (C) a curing agent not having two or more thiol groups, (D) a polythiol compound having two or more thiol groups, (E) a curing accelerator, and (F) an inorganic filler. The adhesive sheet has a mold release base material and an adhesive layer comprising the adhesive composition prepared at least on one side of the mold release base material. The coverlay film has an electric insulation film and an adhesive layer comprising the adhesive composition prepared at least on one side of the electric insulation film. COPYRIGHT: (C)2011,JPO&INPIT
