How it's used
Often associated with crime dramas and police procedural films, this term carries a slightly clandestine or gritty tone. It specifically refers to someone acting as a source of intelligence from within a group, rather than a general spy or secret agent. It is rarely used to describe someone working for a government intelligence agency in a formal capacity.

Common mistake
Do not confuse this with 間諜, which is a more formal or literary term for a professional spy or secret agent. Using 線人 in a formal or professional context might sound like you are referring to a criminal underworld informant.
