PROBLEM TO BE SOLVED: To provide a baked color pencil lead having a sufficient color development and line-drawing density and excellent mechanical strength, i.e., flexural strength, tensile strength, impact strength, etc., and its manufacture process, especially a baked color pencil lead suitable for holders of sharp pencils, etc., and its manufacture process. SOLUTION: The baked color pencil comprises a baked lead body and a coloring material filled in the pores of the baked lead body. Here, the baked lead body is obtained by impregnating the pores of a porous baked lead body, which is made of at least a body material and silicon nitride, with a liquid containing a polysiloxane having a structural unit of formula (I) (wherein R1 and R2 are identical to or different from each other and are each an alkyl group, an alkoxy group, hydroxyl group or a siloxane group), and heating this in an oxidative atmosphere and/or nonoxidative atmosphere.
