The purpose is to provide a heating unit of a carbon fiber-mixed sheet with a low price in which sheet carbon fibers are equally dispersed and a member on the surface of which sheet is not subjected to such change of properties as discoloration and the like. The constitution is characterized in that a sizing agent covers a part of the carbon fiber-mixed sheet which sheet is made by the mixed fiber-making of 5＿10 wt. % of a carbon fiber having a length of 5＿10 mm and 95＿90 wt. % of a pulp containing a bast fiber and in that the sheet has a thickness of 150 μm or less, a basis weight of 50 g/m2or less and a degree of beating of 30＿70° SR.
