Abstract
A silicon carbide porous body contains β-SiC particles, Si particles, and metal silicide particles. The maximum particle diameter of the β-SIC particles is not smaller than 15 μm. The content of the Si particles is not lower than 10 mass %. The maximum particle diameter of the Si particles is not larger than 40 μm. Further, an oxide coating film having a thickness not smaller than 0.01 μm and not larger than 5 μm is provided on surfaces of the Si particles.
