Heat Exchange Element and Heat Exchange Ventilator Including the Same

Abstract

A heat exchange element in which heat is exchanged between two flows respectively passing through spaces 4 and 5 for air supply and exhaust, partitioned with a plurality of members 2 and 3. The members 2 and 3 are bonded with a bonding agent which contains a volatile organic compound or a carbonyl compound but from which the total emission of such a chemical substance is 100 μg/hr or less per gram.
