PURPOSE:To obtain a high-performance filter capable of the washing and the reusing by burying the wave-shaped valley parts with the continuous pores- bearing porous bodies in the air suction sides of one surface of the sheet-like filter members bent nearly to a wave-shape and holding the air blow-off sides of the other surfaces with the rigid network bodies. CONSTITUTION:In the air suction sides of one surface of the sheet-like filter members 9 bent to a wave-shape, the continuous pores-bearing porous bodies 10 are provided so as to bury the valley parts and the wire gauzes 11 are pro vided to the air blow-off sides of the other surfaces of filter members 9. There fore the dust-laden air reached to one surface of the filter members 9 is entered into the insides of the filter members 9 from the whole parts of the surface. Since the dust-laden air is passed through the continuous pores of the continuous poresbearing porous bodies 10 to purify it and successively the dust is separated and collected by the filter pores of the filter members 9, it is highly purified.
