PROBLEM TO BE SOLVED: To realize an easily breakable sheet wound around the outer periphery of a solid drawing material main body without lowering the workability at its manufacturing and the handleability at its usage. SOLUTION: This solid drawing material 1 is produced by winding a sheet 2, on the rear surface of which an adhesive layer is formed, under the state that the adhesive layer side of the sheet 2 faces the solid drawing material 1. In this case, in the sheet 2, an overlapped part is formed at winding under the state that a low bonding force layer 4 is formed on the surface of the sheet 2 or the solid drawing material 1 side in the overlapped part.
