PROBLEM TO BE SOLVED: To provide a porous carbon material for a non-aqueous electric double layer capacitor which is excellent in high-speed charging/discharging performance and has less expansion of its volume in charging, and to provide a manufacturing method thereof and a non-aqueous electric double layer capacitor. SOLUTION: A metal compound is blended with a coal pitch or a petrol pitch and a blended result is carbonized, and a carbide is cleaned with a solvent capable of dissolving the metal compound to obtain the porous carbon material for an electric double layer capacitor. The coal pitch etc. to be used is preferably has a primary quinoline insoluble component of not more than 2 mass% and the metal compound is preferably an organic acid salt of magnesium. A mass ratio of the metal compound to the coal pitch etc. is preferably 95:5 or 5:95. Preferably, the porous carbon material has an average diameter of micropores of 1 nm-10 nm.
