Abstract
A purging agent that has excellent purging performance without generation of aggregate is disclosed as a purging agent used in a purging operation where a resin to be processed contains a polar group-containing thermoplastic resin. This purging agent contain a hydrocarbon-based resin, and at least one metal salt among an alkaline metal salt and alkaline earth metal salt, has a water content of 0.15% by weight or less, and includes 0.1 to 20% by weight of the metal salt expressed as the metal relative to the hydrocarbon-based resin.
