A method for manufacturing a porous silicon carbide sintered body that includes manufacturing a silicon carbide molded body by using a raw material composition containing at least silicon carbide powder, silicon powder, and a binder. The method further includes carrying out a degreasing treatment on the silicon carbide molded body to manufacture a silicon carbide degreased body, and carrying out a firing treatment on the silicon carbide degreased body to manufacture a porous silicon carbide sintered body. The raw material composition has about 1 to about 3% by weight of the total amount of the silicon carbide powder and the silicon powder in a content of the silicon powder. And, the firing treatment is carried out at a temperature allowing silicon carbide powder to mutually form intergranular necks through counter diffusion.
