PROBLEM TO BE SOLVED: To provide a filter material capable of reducing a pressure loss while maintaining the flow balance of a fluid, capable of being reduced in size as well as weight and manufactured at a low cost, and also capable of being easily deformed into a cylindrical shape or a curved-surface shape without causing exfoliation of a material and fall of powders.SOLUTION: Provided is a filter material 100 configured with a honeycomb plate 110 which is formed with an alternate laminate of a plurality of wave-type sheets 111 and a plurality of base sheets 112 and allows a fluid to pass through between both faces thereof. One or more notch part 113 is provided from one of the faces of the honeycomb plate 110 toward the other face.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】流体の流れのバランスを維持しつつ圧力損失を低減し、小型化、軽量化され低いコストで製造可能であり、かつ、材料が剥がれたり、粉が落下したりすることなく容易に円筒形状や曲面形状に変形可能なフィルタ材を提供すること。【解決手段】複数の波型シート111と複数のベースシート112の交互積層体で形成され両面間を流体が通過可能なハニカム板110からなるフィルタ材100であって、ハニカム板110の一方の面から他方の面に向かって、1箇所以上の切込部113が設けられていること。【選択図】図2
