The present invention provides a paste composition for silicon carbide sintered, a silicon carbide powder, organic binder, and is configured to include a hollow sphere of a mullite material, and the hollow sphere aids in the sintering process forming between connections of silicon carbide particles in the sintered body and the action given in the porous structure provides a paste composition for a silicon carbide sintering. SiC sintering the paste composition of the present invention, it is possible to form a porous sintered body of high strength and porosity of without the need for a separate pore-forming agent and neck kingje, relatively reduce the manufacturing cost of the possible low-temperature sintering bar porous structure can and, since no cracks or the like occur in the sintered body has excellent filtering performance.
