PROBLEM TO BE SOLVED: To obtain a one-component liquid epoxy resin composition which is excellent in airtightness, especially in adhesion to a liquid crystal polymer and to a metal terminal even at high temperatures in a reflow treatment, in a small-sized relay using a liquid crystal polymer as one of constituting materials. SOLUTION: This resin composition, used for the airtight sealing or insulation sealing of a small-sized electronic or electric part, is a one-component liquid epoxy resin composition which does not contain dicyandiamide. More specifically, the composition preferably contains an imidazole compound (excepting dicyandiamide) as a curing agent and calcium carbonate as a filler.
