A multiple tube type separation membrane module characterized in that said module comprises plurality of tubular separation membrane elements 3 having sealed ends and open ends; outside pipes 13 surrounding the tubular separation membrane elements 3 with spaces formed therebetween and having first openings on the sealed ends side of the tubular separation membrane elements 3 as well as second openings 133 in the vicinities of the open ends of the tubular separation membrane elements; means for inlet communicating with the first openings of the outside pipes; first means for outlet communicating with the open ends of the tubular separation membrane elements; and second means for outlet communicating with the second openings of the outside pipes, wherein fluid F<SUB>1 </SUB>flowing from the first openings of the outside pipes through the means for inlet flows in the spaces between the tubular separation membrane elements 3 and the outside pipes 13 , component F<SUB>2 </SUB>separated from the fluid F<SUB>1 </SUB>by the tubular separation membrane elements 3 flows out from the first means for outlet through the open ends of the tubular separation membrane elements 3 , and the remaining fluid F<SUB>3 </SUB>flows out from the second means for outlet.
