Two-dimensional particles, conductive film, conductive paste, and composite material

The purpose of the present invention is to provide two-dimensional particles capable of achieving a conductive film having high conductivity and moisture resistance. A two-dimensional particle according to the present invention has one or a plurality of layers, the two-dimensional particle containing Li atoms, the layers containing a layer body represented by formula MmXn and a modification or terminal T (T is at least one selected from the group consisting of a hydroxyl group, a fluorine atom, a chlorine atom, an oxygen atom and a hydrogen atom) present on the surface of the layer body, M is at least one type of group 3, 4, 5, 6, and 7 metal, and M is at least one type of group 3, 4, 5, 6, and 7 metal. X is a carbon atom, a nitrogen atom, or a combination thereof, n is 1-4, m is greater than n and 5 or less, Li atoms include a first component and a second component having a greater chemical shift than the first component as measured by 7Li NMR, and the proportion of the first component in the total of the fi
