Claim 8:
9. A method of manufacturing a silicon carbide porous body, comprising:
obtaining a sintered body by molding and sintering raw material powder containing raw material metals such as Si, C, and metal silicide; and
obtaining a silicon carbide porous body by performing an oxidation treatment on said sintered body,
wherein said silicon carbide porous body contains
β-SiC particles;
Si particles; and
metal silicide particles,
and wherein the maximum particle diameter of said n-SiC particles is not smaller than 15 μm,
the content of said Si particles is not lower than 10 mass %,
the maximum particle diameter of said Si particles is not larger than 40 μm, and
an oxide coating film having a thickness not smaller than 0.01 μm and not larger than 5 μm is provided on surfaces of said Si particles.
