Zusammenfassung:	An epoxy adhesive composition is provided to be rapidly cured, and to ensure a glass transition temperature of more than 140 °C, resistance to heat of more than 200 °C, and excellent adhesive force. A room temperature curable two-component epoxy adhesive composition comprises (a) a first liquid containing epoxy resin having at least two glycidyl groups, and (b) a second liquid containing a hardener. The second liquid includes an amine-based curing agent; a curing accelerator having -OH, -COOH, SO3H, -CONH2, -CONHR(R shows an alkyl group), -SO3NH2, -SO3NHR(R shows an alkyl group), or -SH; a phenol resin curing accelerator; or an imidazole curing accelerator.
