PROBLEM TO BE SOLVED: To provide an imaging tube capable of easily detecting a light-incident position without being affected by decay characteristics of phosphor. SOLUTION: The imaging tube 1 in one embodiment is provided with a vacuum envelope 10 with a light-incident window 12 and a light-irradiation window 13, a photoelectric face 20 formed on an inner face 12a side of the light-incident window 12, electron multipliers 30 to 32 for multiplying photoelectron emitted from the photoelectric face 20, a first film 40 emitting fluorescence by incidence of electron from the electron multipliers 30 to 32, a second film 50 with nearly a uniform sheet resistivity receiving electron from the electron multipliers 30 to 32, and at least two conductive members 60, 62 electrically jointed with the second film 50. The first film 40 and the second film 50 are laminated at an inner face 13a side of the light-irradiation window. COPYRIGHT: (C)2008,JPO&INPIT
