PURPOSE: To provide an epoxy resin composition capable of giving a cured product having small cure shrinkage, excellent thermal shock resistance and especially high mechanical strength such as tensile strength and flexural strength.
CONSTITUTION: This epoxy resin composition contains (A) a low-viscosity epoxy resin containing a trifunctional or tetrafunctional liquid epoxy resin and having a viscosity of ≤100 poise at 25°C, (B) a liquid alicyclic amine mixture (hardener) produced by adding at least one kind of amine selected from menthenediamine and (4-amino-3-methylcyclohexyl)methane to isophorone diamine and containing 10-90wt.% of isophorone diamine in the mixture, (C) an imidazole compound and (D) metal powder having an average particle diameter of ≤100μm. The amount of the component C is ≥0.1 pts.wt. based on 100 pts.wt. of the component A and that of the component D is ≥200 pts.wt. based on 100 pts.wt. of the sum of the components A, B and C.
