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.
