A packaging member, comprising:

• a first partition plate that is disposed in a containing area for containing a packaged object, and that extends in a first direction;
• and
• a second partition plate that is disposed in the containing area, and that extends in a second direction orthogonal to the first direction,
• wherein
• the first partition plate has a first slit cut therein from an end thereof on one side in an up-down direction,
• the second partition plate has a second slit cut therein from an end thereof on an other side in the up-down direction,
• the second slit is inserted into the first slit to thereby couple the first partition plate and the second partition plate to each other in an intersecting manner,
• the first slit includes a one-side cut surface and an other-side cut surface that face each other,
• the one-side cut surface has an engagement protrusion protruding toward the other-side cut surface,
• the second partition plate has an engagement hole formed therein over the second slit, the engagement hole penetrating the second partition plate in a plate thickness direction thereof, and
• with the second partition plate inserted in the first slit, the engagement protrusion is inserted into the engagement hole to thereby couple the first partition plate and the second partition plate to each other.
