A silicon carbide-based porous body comprising a plurality of silicon carbide (SiC) particles as an aggregate and a binder which binds the silicon carbide particles to each other, wherein the content of the binder, i.e. [100xbinder/(silicon carbide particles+binder)] is 5 to 70% by volume, the open pore ratio is 30 to 70%, and the binder contains at least one member selected from the group consisting of a Ti silicide, a Zr silicide, a Mo silicide and a W silicide, in an amount of at least 60% by volume of the total binder. The silicon carbide-based porous body can avoid excessive temperature elevation when it is used as a filter and the particulate matter (PM) captured thereby is burnt and removed. |
