A laminated filter material for removing foreign materials from gas or liquid with high precision, its fabricating method and a filter using a laminated filter material are described. The laminated filter material comprises a support member of porous metal and a particle layer of fine particles laminated on a surface having asperities of the support member, by immersing the support member in a suspension of the particles without a binder, and evacuating the suspension through the support member. The method for fabricating includes the steps of preparing a suspension of particles finer than the average pore diameter of support member without using a binder, immersing the support member, and evacuating the suspension through the support member. The filter has a housing for supporting the laminated filter material, wherein the housing is provided with a metal attachment part having a surface contacting an end-face of the laminated filter material, and the attachment part and end-face of the laminated filter material are fixed by fusing the particle layer from the reverse side of the contacting surface of the attachment part.
