To provide a filter cloth having high filtration capability and high durability, capable of sufficiently standing temperature at 250°C which is the general temperature upper limit of an incineration flue gas, and showing no shrinkage or expansion.

This heat resistant filter cloth comprises a substrate cloth 2 of totally a texture of glass fiber. Polytetrafluoroethylene fibers of 1.0-10 d are used as a raw material of batting to be formed on the substrate cloth 2 and the substrate cloth 2 and the butting 3 are intertwisted and integrated by needle punching and the resultant intertwisted and integrated filter cloth is thermally shrunk to give this heat resistant filter cloth.
