PROBLEM TO BE SOLVED: To provide a filter material for food product, which has reduced powder leakage, and has excellent heat-sealing workability, sealing strength, stiffness, etc. SOLUTION: The filter material for the food product consists of a laminated non-woven fabric obtained by laminating and integrally thermally compressing a polyester-based fiber layer A having a high melting component and a layer B containing a polyester-based fiber having a melting point lower than the melting point of the constituting fiber of the layer A by ≥30°C, and the laminated non-woven fabric has a unit weight of 10-50 g/m2, a powder leakage rate of ≤10%, and a hot tack strength at a heat-sealing temperature of ≥1 N/25 mm.
