Abstract
A silicon carbide-based porous material containing silicon carbide particles () as an aggregate and metallic silicon (), wherein the average particle diameter of the silicon carbide-based porous material is at least 0.25 time the average particle diameter of the silicon carbide particles (), or the contact angle between the silicon carbide particles () and the metallic silicon () is acute, or a large number of secondary texture particles each formed by contact of at least four silicon carbide particles () with one metallic silicon () are bonded to each other to form a porous structure. This silicon carbide-based porous material can be sintered, in its production, at a relatively low firing temperature and, therefore, can be provided at a low production cost, at a high yield and at a low product cost.
