1. A total heat exchange element comprising:
a plurality of partition members made of a material that contains cellulose as a main component, the partition members being configured as flat sheets, and the partition members being stacked with a predetermined distance therebetween;
a plurality of spacing members made of a material that contains cellulose as a main component, one of the spacing members being disposed between adjacent ones of the stacked plurality of partition members to maintain the distance therebetween; and
an adhesive portion bonding each one of the plurality of spacing members and the respective adjacent ones of the plurality of partition members together,
the total heat exchange element having a first air flow path and a second air flow path, the first and second flow paths being alternately formed with one of the plurality of partition members interposed between the first and second air flow paths, and
the adhesive portion containing, as an adhesive component, cellulose having a smaller diameter than both of
the cellulose forming the plurality of partition members and
the cellulose forming the plurality of spacing members, and
the cellulose as the adhesive component of the adhesive portion including
cellulose which is hydrogen-bonded directly to the cellulose forming the plurality of partition members and
cellulose which is hydrogen-bonded directly to the cellulose forming the plurality of spacing members,
the cellulose of the adhesive portion being hydrogen-bonded directly to the cellulose forming the respective adjacent ones of the plurality of partition members to join each of the adhesive portions to the respective adjacent ones of the plurality of partition members, and
the cellulose of the adhesive portion being hydrogen-bonded directly to the cellulose forming each one of the plurality of spacing members to join each of the adhesive portions to the respective ones of the plurality of spacing members.
