A resin having a nitrogen-carbon-sulfur bond is disclosed. The nitrogen-carbon-sulfur bond is composed of a nitrogen atom, a carbon atom and a sulfur atom, and the atoms are bonded in this order, and a bond between the carbon atom and the sulfur atom and a bond between the carbon atom and the nitrogen atom are at least one of Is a single button. When the number average molecular weight of the resin is Mn, and the number of sulfur atoms constituting the nitrogen-carbon-sulfur bond contained in one molecule is n1, Mn is 500 or more, and Mn/n1 is 50 or more and 300 or less. |
