Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a device which is capable of continuously impregnating porous members with a liquid substance in a short time. SOLUTION: A device 40 for carrying the porous member and a liquid current generating means 22 for making liquid current pressure act on the moving porous member 50 are installed under a liquid surface in an impregnating tank 10 storing an impregnating liquid and, further, a deaeration tank 30 covering the liquid surface to which air (air bubble) coming from holes bleats is provided and the inside thereof is evacuated. In such a manner, positive pressure acts on one side of the porous member and negative pressure acts on another side thereof and thereby deaeration and impregnation can be done in a shorter time than heretofore and the treated porous members are continuously carried out by the carrying device.
