PROBLEM TO BE SOLVED: To shorten antigen measuring time, and to enable highly accurate measurement, by measuring an image of an antigen separated by using this separator, by providing the antigen separator capable of securing a fluid body processing quantity corresponding to the necessity, by solving the problem of dust clogging when separating the antigen. SOLUTION: This antigen separator has an introducing port 1 of a sample fluid including the antigen, a reaction part 3 separating the antigen by antigen/antibody reaction by arranging a plurality of antibody beads on a bottom surface in a microchannel having a rectangular cross section for flowing the sample fluid, a sample fluid introducing passage 4 communicating the introducing port with the reaction part, and a discharge passage 5 of the sample fluid. The introducing passage has an air introducing port 11, and comprises the antigen enriching function by layer separation of an air layer and a sample fluid layer in the vertical direction to the bottom surface by simultaneously introducing the sample fluid and air in the same horizontal plane. An image measuring device is provided above the reaction part. COPYRIGHT: (C)2009,JPO&INPIT
