Abstract
A method for manufacturing a paste for forming a thick film is provided, in which undesired lump materials are efficiently removed from the paste for forming the thick film. The paste, which contains a solid material and an organic vehicle and has a viscosity in the range of about 1 to 50 Pa·s, is filtrated with a sintered metal type filter manufactured by integrally sintering a nonwoven fabric filter part, having a thickness of many folded linear metal fibers and having a mesh opening size of about 1 to 20 μm, and a wire gauze part composed of metal wires knitted into the shape of a mesh.
