Abstract: A detection system of a test substance, includes: a magnetic body that is modified by a first substance capable of being bound to the test substance at a first binding site of the test substance; a marker that is modified by a second substance capable of being bound to the test substance at a second binding site of the test substance, the second coupling site being a different site from the first binding site; a development medium that has a flow passage into which liquid, in which the magnetic body and the marker is dispersed, flows due to a capillary phenomenon, the development medium having a detection position for detecting the marker in a portion of the flow passage, the development medium having light transparency at least in the detection position; and a magnetic force generating portion that is equipped in the development medium.
