<P>PROBLEM TO BE SOLVED: To provide a liquid epoxy resin composition which allows the cured article thereof to have low elasticity and high toughness while keeping the liquid property and reactivity caused by making the viscosity low. <P>SOLUTION: The epoxy resin composition is a liquid at a normal temperature and contains as a composition component (a) an epoxy resin which is liquid at a normal temperature, (b) a polyvinyl acetal-based modifier, (c) a curing agent and a curing accelerator and (d) a filler, wherein the blend ratio of the polyvinyl acetal-based modifier is in the range of 0.5-20 pts.mass per 100 pts.mass epoxy resin liquid at normal temperatures and 0.5-7 mass% per total quantity of the liquid epoxy resin composition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
