Abstract: The present invention relates to an electron multiplier and others to effectively suppress luminescence noise, even in compact size, in which each of multistage dynodes has a plurality of columns each having a peripheral surface separated physically, and in which each column is processed in such a shape that an area or a peripheral length of a section parallel to an installation surface on which the electron multiplier is arranged becomes minimum at a certain position on the peripheral surface in the column of interest.

Abstract: The present invention relates to a photomultiplier having a structure for making it possible to easily realize high detection accuracy and fine processing, and a method of manufacturing the same. The photomultiplier comprises an enclosure having an inside kept in a vacuum state, whereas a photocathode emitting electrons in response to incident light, an electron multiplier section multiplying in a cascading manner the electron emitted from the photocathode, and an anode for taking out a secondary electron generated in the electron multiplier section are arranged in the enclosure. A part of the enclosure is constructed by a glass substrate having a flat part, whereas each of the electron multiplier section and anode is two-dimensionally arranged on the flat part in the glass substrate.
