Abstract: A detection cell includes a pair of filter electrodes, disposed separated from and opposing each other. One of the pair of filter electrodes includes a first region provided following a flow direction of an object of measurement introduced between the filter electrodes, and a second region that is provided arrayed with the first region regrading an intersecting direction intersecting the flow direction, and that protrudes to a position at which a distance of separation as to another of the pair of filter electrodes is smaller than that of the first region. First and second downstream-side electrodes are respectively disposed on downstream sides of the first and second regions, in the flow direction, and are separated from each other regarding the intersecting direction. First and second opposing electrodes are disposed on the downstream side from the other of the pair of filter electrodes, and oppose the first and second downstream-side electrodes.
