Abstract: The present invention provides a filter cloth for a dust collector which shows low pressure loss, no clogging, superior dust shaking-off performance, and durability for continuous use without impairing collection performance, even under such dust collection conditions as high speed filtration and high dust concentration. The filter cloth for a dust collector relevant to the present invention is a filter cloth which is made by laminating and integrating a filtration layer of a nonwoven fabric layer consisting of a thermoplastic fiber and a support layer consisting of a woven fabric layer, characterized in that at least filtration surface layer of said laminated and integrated filter cloth has a concave-convex shape having a height from hill part to trough part of 1.6 to 20.0 mm.
