To provide a carbon sheet of good quality which can be mass produced with good efficiency without allowing a carbon based fine powder to peel and fall from a sheet or a nonwoven fabric of a resin such as a polyester.
A fine carbonaceous powder 2 such as charcoal and active carbon is mixed with an aqueous dispersion of a polymeric compound such as an inorganic coating material and stirred, and then a polyester sheet 1 is coated and impregnated with the resulting dispersion, heated and pressed to allow the fine powder 2 to adhere to the polyester sheet 1 and dried. As a result, the fine powder 2 on the polyester sheet 1 neither partially becomes thin in thickness nor peels and falls from the polyester sheet 1, and the carbon sheet 3 can be mass produced with good efficiency.
