Ventilation member and ventilation structure

A ventilation member comprising:

• a first metal body including a flat portion having a first through-hole formed therein;
• an air-permeable membrane having a first principal surface and a second principal surface and placed on the flat portion of the first metal body so that the first principal surface covers the first through-hole;
• a second metal body including a flat portion having formed therein a second through-hole separated from the first through-hole by the air-permeable membrane, the second metal body being placed on a second principal surface side of the air-permeable membrane so that passage of air is permitted between the first through-hole and the second through-hole through the air-permeable membrane;
• and
• a joint portion including a structure in which a projection of the second metal body is fitted in a recess of the first metal body, the joint portion fixing the first metal body and the second metal body to each other with the air-permeable membrane held between the first metal body and the second metal body,
• wherein the air-permeable membrane has a portion located outwardly of an outer end of the flat portion of the first metal body and an outer end of the flat portion of the second metal body.
