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.

Abstract: A detector device includes a pair of filter electrodes, a collector electrode collecting charged particles that pass through a space between the pair of filter electrodes, and a detection circuit connected to the collector electrode and detecting an amount of the charged particles that are collected. The collector electrode includes an upper electrode layer having a collection surface that receives the charged particles, a lower electrode layer that is disposed opposite a surface of the upper electrode layer that is an opposite surface from the collection surface, and an insulation layer having an insulation property and disposed between the upper electrode layer and the lower electrode layer. The detection circuit is configured to be connected to one of the upper electrode layer and the lower electrode layer.
