Zusammenfassung:	Provided is a composite material that shows a low specific dielectric constant, and that hardly causes an appearance failure or changes in characteristics when exposed to, for example, a treatment liquid to be used in the production of an electronic circuit board. Specifically, a plate-like composite material including polytetrafluoroethylene and a predetermined filler, and satisfying a predetermined condition serves as a composite material that shows a low specific dielectric constant, and that hardly causes an appearance failure or changes in characteristics even when exposed to, for example, a treatment liquid to be used in the production of an electronic circuit board.
