<P>PROBLEM TO BE SOLVED: To provide a porous body with a separation membrane which has a high permeability rate as a whole porous body with the separation membrane even when having two or more tubular passages. <P>SOLUTION: The porous body with the separation membrane 1 is equipped with two or more tubular passages 11 where the separation membrane having a separation function is formed at an inner wall of a through-hole provided at the porous body 12. At a cross section which is perpendicular to a longitudinal direction of the tubular passage, all tubular passages face an outer circumferential surface y of the porous body with the separation membrane. <P>COPYRIGHT: (C)2013,JPO&INPIT |
