PURPOSE: A silicon carbide filter for filtering exhaust gas of an engine is provided which easily removes silicon during manufacturing of porous silicon carbide by adding a reinforcing additive increasing a contact angle between sintered compact and silicon, and a manufacturing method of the silicon carbide filter is provided. CONSTITUTION: In a porous silicon carbide filter for filtering exhaust gas of an engine which is manufactured by the processes of forming compact by mixing silicon carbide powder and carbon powder with a liquid phase solvent and polymer, evaporating the liquid phase solvent and polymer by applying heat to the compact, sintering reacting carbon and silicon by pouring high temperature molten silicon into the solvent and polymer removed compact, and removing residual silicon by heating the sintering reacted compact, the silicon carbide filter(4) for filtering exhaust gas(1) of an engine is characterized in that a reinforcing additive is added into the mixture to increase a contact angle between the reaction sintered compact and the silicon in the process of forming compact by mixing silicon carbide powder and carbon powder with a liquid phase solvent and polymer.
