The present invention provides a dust collector which includes a chamber divided into an inlet chamber and a discharge chamber by a barrier, and a bag filter which is installed inside of the inlet chamber, and is formed in a shape having an inner space and an opening part by a filter medium, so as to communicate with the discharge chamber through the opening part, wherein a treatment gas is introduced into the inlet chamber and is filtered while passing through the filter medium of the bag filter, then moves to the discharge chamber through the opening part to be discharged, and the bag filter has air permeability decreased toward the opening part. According to the bag filter and the dust collector, it is possible to achieve a high collection performance and a stable operation even when using a long bag filter due to improvement of uniformity of the filtration velocity along the length of the bag filter.
