ABSTRACT:
A photomultiplier which can be easily made compact has a dynode unit constituted by stacking a plurality of stages of dynode plates in an electron incident direction in a vacuum container constituted by a housing and a base member integrally formed with the housing. Each dynode plate has an engaging member engaged with a connecting pin for applying a voltage at a side surface thereof. Through holes for guiding the connecting pins from the outside of the container are formed in the base member. Each engaging member is arranged not to overlap the remaining engaging members in the stacking direction of the dynode plates. The arrangement position of each engaging member and the arrangement position of the through hole for guiding the corresponding connecting pin to be connected are matched with each other.
