To provide a method for generating carbide, with which the initiation of generating carbide can be efficiently put in practice.

Before charging refuse Q into the inside of a carbide generator 1, a porous inorganic particulate P is charged until the electric heating elements 12 provided in the carbide generator 1 are covered. Since the refuse Q piled on a heat-storage layer comprising the porous inorganic particulate P is evenly heated by the heat-storage layer regardless of the number or layout of the electric heating elements 12, generation of carbide can be efficiently put in practice without uneven heating.
