1. a filter filtration material, former for filter material material bends in many places and is formed as folded shape and forms by it, the former material of this filter material comprises porous layer for trapping the particle be filtered contained by gas and is bonded in the substrate layer at least one face of this porous layer, it is characterized in thatThis filter filtration material comprises:

  • Multiple bend, the plurality of bend is formed by being bent by former for described filter material material;

    Multiple flat part, the plurality of flat part is formed by the region except multiple bend in the former material of filter material and configures in the mode of face-off;

    AndMultiple intervals maintaining part, in the side, a face of the former material of filter material, the plurality of interval maintaining part is formed between each flat part, in the another side side of the former material of filter material, this interval maintaining part is formed between each flat part, for keeping the interval between adjacent flat part and adjacent flat part being linked up each otherEach interval maintaining part of each interval maintaining part being formed at the side, a face of the former material of described filter material and the another side side being formed at the former material of filter material to be formed across the mode of each flat part overlap,Peel strength when porous layer in the former material of filter material and substrate layer are stripped is more than 0.4N, and make each flat part of being linked up by interval maintaining part mutual separated time peeling strength be 0.6N ~ 3N.
