摘要： The present invention relates to a photomultiplier having a fine configuration capable of realizing stable detection accuracy. The photomultiplier has a housing whose inside is maintained vacuum, and a photocathode, an electron-multiplier section, and an anode are disposed in the housing. In particular, one or more control electrodes disposed in an internal space of the housing which surrounds the electron-multiplier section and the anode are electrically connected via one or more connection parts extending from an electron emission terminal of the electron-multiplier section. In this configuration, due to a voltage, instead of the applying between an electron entrance terminal and the electron emission terminal of the electron-multiplier section, being applied between the electron entrance terminal and the control electrodes, an electric potential gradient which is increased gradually from the photocathode side toward the anode side is formed in the electron-multiplier section, and a sufficient electric potential difference is provided between the electron emission terminal of the electron-multiplier section and the anode, which makes it possible to obtain stable detection accuracy.
