A bag filter for a filter dust collector is provided to maximize dust collection efficiency by increasing a filtration area of a filter bag having a cross section of a saw tooth shape. A bag filter for a filter dust collector comprises a bag cage(10), a filter bag(20), a upper end cap(30), and a lower end cap(40). The bag cage includes a plurality of ring wires(11) and a plurality of vertical wires(13). The ring wire has a saw tooth shape. A mountain-shaped protrusion(11a) is formed in the ring wire. The vertical wire is welded in the mountain-shaped protrusion of the ring wire. A top and a bottom of the filter bag are opened. The bag cage is inserted inside the filter bag. The filter bag has a cross section of a saw tooth shape. The upper end cap finishes the top of the filter bag and the bag cage. The lower end cap finishes the bottom of the filter bag and the bag cage.
