PROBLEM TO BE SOLVED: To provide a sheet for a dust collection filter composed of woven cloth of mutually fusing both of warp and weft at a crossing point by being used as the warp and the weft, and capable of easily removing once-collected dust-dirt.SOLUTION: The sheet for the dust collection filter includes the woven cloth 1 of fusing the warp 11 and the weft 12 at the crossing point, and in the sheet for the dust collection filter, the warp 11 and the weft 12 are core-sheath type composite fiber whose sheath part has a melting point lower than a core part, and a wire diameter A and a wire diameter B in an unfused part of the respective warp and weft and a thickness C of the woven cloth, satisfy the following formula of C/(A+B)<1.00, and a separation distance a1 and a center distance a2 of the adjacent warp, a separation distance b1 and a center distance b2 of the adjacent weft, satisfy the following formula. (a1×b1)/(a2×b2)>0.60. |
