PROBLEM TO BE SOLVED: To obtain a sealing material which is excellent in storage stability, flexibility after curing, and adhesion to substrates and quickly cures by moisture at normal temperature by compounding a specific heterocyclic compound with a polyepoxy compound as a latent curing agent. SOLUTION: This sealing material comprises a heterocyclic compound having at least two heterocyclic groups represented by the formula and a polyepoxy compound. In the formula, R is a 2-10C linear or branched alkylene group optionally containing O and/or S; R1 and R2 are each independently H, a 1-6C linear or branched alkyl or alkenyl group or a 6-8C aryl group provided they may combine with each other to form, together with a carbon atom to which they are bonded, a 5-7C cycloalkyl group; and R3 is a 1-10C alkylene. Examples of the heterocyclic compound are the ones having main chains selected from among hydrocarbons, polyethers, or the like, having hydroxyl groups on the side chains.
